Hey everyone ok so as the title states my engine seems to be having a random missing problem... happens in park, in neutral, in drive, on load, at idle lol... but its a pain cause its just so freakin random...

Ok so filled up fuel in the car last sunday, by sunday arvo the car had started missing. All week driving to and from work etc the car would randomly miss and when it did miss it would either miss 3 or 4 times in quick succession or just a random miss and then go back to normal. This was either under load or sitting at a set of lights or even after just starting the car.

Sometime during last week i filled up fuel again and it still did the problem but looking back Im not sure if it did it more or less. I make a point to mention that as i filled up fuel again on monday night (yes i drive a lot lol) and then noticed that the miss was becoming quite rare. I dropped the car into the mechanics on Tuesday who couldnt get the car to produce the skippin at all. Tuesday nite driving home it missed, this mornin drivin to work it didnt, this evening drivin home it did it prob 4 times max but not in quick succession as it has previously done.

The leads have been checked no probs, the dizzy cap is new and connections are fine, the ignition coil is also new and the connections are fine too... could it possibly be a case of bad fuel that may have caused this? any advice or suggestions would be greatly appreciated :D

Thanks
Rav

umm change fuel filter if it doesnt help least u know its new :P

timing belt hasnt sliped a tooth or anything?

lol i had simular problem but i found mine next day lol a spark lead decided to jump off but damn it had a nice note under load sounded kinda like a wrx LOL :p sry just had to say it lol

yeak im gunna blame fuel aswell.. replace filter asits cheap and see what happens..:)

Maybe it needs a drink of Vindaloo to flush it out..:P

Do the magna's have a guaze filter in the tank like most EFI cars do ?

No, idea but i'm going with the rest of these fools. Do your fuel filter, but really, if its bad fuel - your car would run like trash all the time and if it doesn't have a good octane level you'll be knocking and having trouble idling and it'd have to get up.

Replace your plugs and leads. use 8mm or 10mm leads if your not already and try NGK platinum or iridium. that fixed my missing problem

big 4

hopefully you dont use shell fuel cos i hear it has the most water in it.

it already has brand new plugs n brand new leads... lol...

ok update... reversed car out of driveway this mornin n it stalled wouldnt start grrr rolled it back down the driveway (ive gota 50m driveway). checked the connections etc restarted and it fired up...ok so drove it down the street then it started stutterin n back fired n died... great... made a few calls then thought i wonder if it would start n sure enough it did, so legged it back home got it in the carport and it died again... and now it wont start... hmmmm....

Have you checkled all the elctrical connections in the engine bay particularly:-

Plug into distributor
Plug into TPS
Plug into ingition coil
Plug into air flow meter.

These corrode over time and give intermitent problems... a good clean with a thin file into the terminals and a spray of ELECTRONIC CONTACT CLEANER NOT WD40 or some other pentrating oil may solve your problem.

Wont take long to check either way .....

hopefully you dont use shell fuel cos i hear it has the most water in it.

i heard bp had that problem. friends dad is a mechanic and it actually did happen, huge bill, they paid up though. i only use shell so better not be that lol

I'm with the others that it is the fuel filter. I'm also a Shell user, and have not had any problems, and that is in Australia and the USA.

Just in case there is some water in the fuel, add some methylated spirits into the tank, as that will separate the water from the fuel, and make the water float on top, and eventually will evaporate. Fill the tank up with the highest octane fuel to help remove whatever crap maybe in the fuel system from tank to ignition.

well just another update..

did the spark plug testy thingy to see if there was a spark present... there wasnt... then tested the ignition coil n yes it produces a spark but nothin coming from the dizzy itself though back along the leads to the spark plug.... fuel seems to being working ok in terms of fuel pump issues but will hopefully b chaning the fuel filter 2nite....

with regards to the fuel im currently running Shell Racing as well as a bottle of injector cleanerl...

any other suggestions guys? keep em comin please!!

Rav,

If the coil is producing spark, but the plugs aren't, your problem is somewhere between the distributor and the plugs for certain (assuming your coil HT tests were sound).

Did you test for spark at more than one plug (and, did you test using the plug or the lead itself?)? Did you test for spark from the coil at the distributor end of the coil HT lead? If you are *certain* these two tests were carried out correctly (and you tested for spark at the leads, as opposed to the plugs), the problem *has* to be isolated to the distributor cap, rotor button or leads ;-)

Cheers,
Mattt.

well another update... 96Altera came round, along with QMD///801... we changed the fuel filter but it wasnt that dirty in terms of solids however there was a lil bit of dark liquid coming out... Craig did the sparky lead test thing via the lead only, not the spark plug and heres the weird thing... sometimes it would spark then at later stages it wouldnt... the coil would spark then it wouldnt... the dizzy was examined thoroughly, pin removed and checked and nothin could b found to indicate there was a failure there.... the ignition coil was checked as well and it seemed to be sparking fine... we spent quite a bit of time checkin sooo many things but it still persisted on doing it... so we gave up and decided to book the car in to an auto elecy for them to read the codes however we thought let's disconnect the battery and reset the ecu just for arguments sake.... the prob now seems to not exist :confused: drove the car round quite a bit with as much on as possible and tried to keep it under load but no missing etc... ill drive the car tomorrow and see how it goes i guess...

big thanks to craig and qmd///801 though, we may not have fixed the prob but thanks heaps for all your help this evenin... (and for your help to come too lol)....

one of my plugs was dead and it was randomly missing like that, i know what you are talking about as well, and my plugs were 2000ks at the most, it was time to change the leads with it anyway, so i did the whole plugs/leads/dizzy cap and rotor all at the same time. havent had a problem since..

and for your help to come too

O RLY?

Coil or rotor..


Coil packs can be a ***** sometimes and only work when they want..:)

Hi

When you put the new D/cap on did you replace the Rotor Button?

I would go there. Please be aware that if you used a Repco cap they did have a manufacturing issue (gen 2 models) and I had 3 NEW ones before it stopped missing. All replaced by Repco under their 20,000km warranty.

Check this and the rotor button.

Can you see any sparks under the bonnet at night time? This is a good check.

There's an old mechanics saying ... 90% of fuel problems are electrical.

Hope this helps

Hey peeps....

Car started this mornin fine....... and then died... so prob is still present... Craig did a few tests on the ignition coil and the dizzy cap and rotor and beleives its all ok but he's not 100% sure though... the Dizzy cap is from repco too btw... ive booked the car in on Monday to go to the auto electrican to run some tests on so i guess we'll have to wait and see..... any other suggestions in the meantime?

Thats d cap thing for repco sounds dodgy..

Hi

The Distributor cap cap issue from Repco was a manufacturing fault and it all depended where the cap eneded up in which store across Australia.

Many Repco dealers had no idea of the issue if they had not encountered the problem.

The error was confirmed with Repco. After a new cap and rotor was installed and run for about a week, the cap still continued to miss fire. On close inspection, in a brand new cap, there were fine lines of what appeared to be carbon running from one or two terminals to the centre earth electrode.

This caused arcing and the misfire. The ironical thing was that the mis could basically turn up at anytime. I guessed that as the rotor reved to thousands of revs that the carbon blew away then built up again.

On closer inspection there appeared a fine layer of what appeared to be black dust (carbon) around the inside circumference of the cap between the electrodes, again causing indisriminant mis firing.

Eventually all was corrected as were the caps from Repco, but there can still be some out there on the shelf or in stores.

I have read a few comical posts here about the gen 2 Magnas and there distributor caps and they are all true, with tongue in cheek .... like - if the seatbelt sticks - change the distributor cap, if the window sticks going up and down - change the distributor cap, if the mrs farts - change the distributor cap.

This problem may not be the distributor cap for you, but it is worth a very close examination, because it only takes a couple of pieces of crap in the cap to cause a crappy day, week or night.

Hope this helps.

im having similar problems. check my thread in tech torque http://www.aussiemagna.com/forums/showthread.php?t=46928

I believe my problem lies in the distributor cap (if it has one, havent looked) or fuel delivery. so filter or pump blockage as it is misbehaving when idling, the revs drop very intermittently but very noticable. and also sometimes really really struggles to accelerate

well the cars at the auto electricain atm... over the guess work n just want my car back on the road.... lol... i should mention the dizzy cap was replaced bout 3 months ago along with the ignition coil and there was no prob with anythin until as mentioned in the openin post...

ill keep you all in the loop as soon as i know whats the situation...

It wouldn't be carbon deposits or dust in the cap, as i removed the cap completely and cleaned it with a cloth, including the contacts and the pin.

The coil was firing through the cable that goes into the cap. I got zapped quite good with it too. lol

Good luck with the auto sparky. Keep us up to date with what they find

well $205.00 later and my car seems to have kicked its habit... i hope :redface:

Dropped the car off Monday morning, didnt skip or stall or anythin all the way there, I thought oh great here we go. Get a call from the Auto Elecy that arvo advising me that the codes are there but its not doin the issue so they are keeping it over nite. They store it across the road in the Battery shop and when they drive it across the road the next mornin thank god it stalls and skips lol...

So they run more tests with the sensor tool and discover that a wire in the air flow sensor has been skinned and is rubbin up against another wire and causin the skippin prob as well as the stalling etc. Thats it. I get a call that arvo from the place again sayin its all good but he would like to drive the car home 2nite and to work again to see if the car is def running 100%.

Sure enough the car didnt do anythin at all. Picked it up this arvo and eveythin seems to be runnin beautifully soooo fingers crossed it stays that way. Thanks to everyone for your comments and suggestions and ideas on what to try, very much appreciated.

Massive thanks to 96Altera for havin the patients to come out and see me nearly every day to see if we can work out the prob. Big thanks also to Ol' Fart for your help, and Pete for lending me your old car while mine was off the road.

Rav

Well done that needs a "sticky"

I get a call that arvo from the place again sayin its all good but he would like to drive the car home 2nite and to work again to see if the car is def running 100%.

You mean, He wanted to go pimpin' that night and try to pick up?

well.... drove the car to work this mornin...... its still missing and dies on me..... :rant: :rant:

Did you ask the eleckys what error codes were on the computy ?:confused: :)

Did you ask the eleckys what error codes were on the computy ?:confused: :)

he said 3 errors were showing up... one was the air flow meter one was the barrometric senor and i forgot what the 3rd thing was but it too was related to the air flow meter plug thingy.....

I wonder if yur AFM is faulty, or maybe the connections in that plug you've got cable tied on :D

I think I have a spare AFM here, if I can find it i'll take off the shroud (ive still got the photos from bribie when they put the pod filter on :shock: ) and send it to ya.

Its worth a shot :D

you're a legend buddy :D

Get the codes

Hey rav! have you considered taking it to a Mitsubishi Dealer?:think: I know that they are not the cheapest on the block, but they will find the problem i am sure, as they are in the know!
I just had the magna serviced on monday, stung me for a bit, but it was well worth it, she is purring like a kitten:clap:Hope it gets sorted real soon, cheers:cool:

Update... changed the AFM with thanks to Big4Cyl... prob still exists... badly.... ever had your car stall on you on the freeway lol lucky it was at midnight i guess.... anyone have a big ass sledgehammer i could use for a few hours....

does it happen when the engine is at temp?
maybe the bushed in your dizzy are shot.....

like i said before... kick it! works every time. if not... there is nothing that sticky tape cannot fix lol.
sorry to here that hey rav.. time for some big dosh to be spent...

well.... drove the car to work this mornin...... its still missing and dies on me..... :rant: :rant:

Did you pay the autoelec? I wouldn't have since he didn't do jack****.

When i picked it up the afternoon before the prob was there, even for the auto elec, drove from Browns Plains to Mt Gravatt, Mt Gravatt to home and there was no probs. then the next day is when the prob returned... its that random...

Yeah it does happen at temp...

check out my thread about those wonderful mitsubishi dealerships before taking your car to one...

another update... lol...

started the car this mornin to drive out of the garage to take to the auto elecy, it died n rolled out then wouldnt start. Auto Elecy sent round a tow truck to pick the car up at their cost too... get a call during the day saying that the wires going into the ignition coil (the side opp the lead coming from the dizzy) had fried and they replaced that and the car was running fine... sooo i told him to keep the car overnite and to take it home, again, to test it to see if the prob is still present.... im sooooo over this....... i bet it doesnt do it for him at all and when i get it back 2morrow it happens... anyone wana place any bets?

yet another update lol....

picked up the car this morning.. didnt hesitate or stall etc for the mechanic at all last nite or this morning.. drove it to work this morning and it didnt do anythin either soooo fingers crossed the problem has been corrected... fingers crossed.....

Hmm i need to cut some more wires then... :shifty:

Damnit..... looks like they messed up my plan of sabotage:rant:
hahah good to hear rav, hopefully u'll be running on the dyno now
