hey guys
just did a servie on my TH.
did oil filter and new oil
New Plugs (no leads in stock to used old ones)
and also installed pod (not looking for increase but was same cost with adaptor and filter as the stock one and give some noise)

bolted it all back up and now i feel i have a vacum leak some wear but as its getting dark not sure, when my car is idling its got bit of a miss and when cruisin its def got a miss now. when i got home i could here a bit of a high pitch noise sounding like a leak.

so should i have changed the manifold gasket or was it ok to reuse?

where should i start to find my problem....

hi reusing the gasket is ok as long as you use silicon on it not to much but you could have changed it they are cheap enough , and have a good look over what you have undone and then reconected you might have missed some thing or also one of the old plug leads might be stuffed
hope this helps some if you have any more problems and you are in ashwood area i can have a look and help you out my contact number is 0410999646

not quite sure where ashwood is i am out on west

This is EXACTLY what I am talking about when people post up wrong information

Liam, you are trying to help mate but you clearly do not have a clue here. Are you going to replace his cat and oxy sensor when your silicone stuffs them up, I thought not!!!!

DO NOT USE SILICONE AND IGNORE THE ABOVE POST PLEASSSSEEEE!!!!!!!

You DO NOT have to use anything, the top manifold gasket is a metal pressed gasket and can be use many times over

Check you did not split your booster hose, you have reconnected your vac hose to the fuel pressure reg and also the one on the back to the carbon canister

If you took off your TB, check you have placed the gasket back on the TB correctly as these only go on 1 way, they will bolt up several ways but only 1 way is correct

If you have a vac leak you will also have a high idle, do you have this also?

Cheers Mal, wouldnt use silicone on me car dont paninc.....
i have a feeling i may have split or not put one of the hoses on the throttle body/intake pipe.
its bit to dark to see now. but will check tomorrow morning.

idle is maybe a little higher... but not much that i noticed.. just bit up n down... more of a miss than high..

Mal might be able to fill in why the following happens, I just know it does through a couple of my cars having these symptoms:

Leads issues generally only appear under load. That is in drive or in gear. In Neutral the 'miss' and rough idle tend to dissapear - but once in gear and accelerating the 'miss' re-appears. Thats how I test if its a leads issue or something else.

Apart from that as per Mal's post.

You'd be suprised - you may have CRACKED a spark plug when puting them in, it happens, more common than you might think.

may be leads. as idle seems ok.. just has rough idle in gear and has a miss when crusing at 100km/h in drive..

when u up the revs around the streets no issue whats so ever.

Ok could explain my post a bit better aswell.

Bad/Damaged/Broken leads will have a miss under load (possibly while idling in drive), felt while accelerating. Feels like the engine 'stutters' for lack of a better description.

However if you put it in Neutral, and give it a rev - its all fine, no stutter, no hesitation, no miss.

This being said, im certain Madmagna is on the money.

in neutral and giving it a rev its fine... no probs

in drive bit of a miss when stopped... and but of a stutter if i take off slow or cruise it has a jerk and miss

sounding like leads?

Sounds like the issues I had when I replaced my leads.

Done a full service, so didnt think it could be leads. Ended up replacing rotor cap/button/fuel filter trying to chase this down. Turns out I had faulty leads. Only buy bosch from now on.

Look to me it sounds a lot like a issue with the leads. Firstly - check to make sure none have partially come off (especially the rear one's, with new leads its more common, as the new silicone is somewhat slippery).

I'd then check the distributor, make sure none of the leads are partially off*

* The main reason why im hesitant on saying 'yeah mate its the leads just replace them' is simple, a) they are not exactly cheap b) they are a pain in the backside to change, especially since you just changed the plugs. Madmagna has been working on cars for quite some time, he might know of another issue that causes the same symptoms which could be as simple as a gasket or a hose.

well i should have replaced the leads but they didnt have any in stock. so going now to another shop to see if i can get some..
so will change them if they have them in stock and go from there

$112 later new leads are now on.. is bit better but still rought...

would changing the air filter to a pod make it have a miss?

On similar note does anyone know which fuel filter magnas take and where it is?

can u post up a pic of the POD filter you installed, if its those crappy round ones with the hole in the middle there is your problem.
only ones that will work on our cars are the oval ones, that said i wouldnt even stick that on, if it was open in the engine bay, only boxed or relocated behind the front bar perhaps.

will try take pic and put it up.

what is the differents between an oval filter and a cone shaped one?

the round one creates a swirling affect (apparently) and this confuses the MAF sensor, the oval ones do not.
put your old filter back in, you are better off buying a K&N pannel.
i have one, they last forever

Hrm, forgot out the round filters aswell.

There was some threads (1year ago?) about people having issues with round pods. Oval one's work, round one's as per above.

thats a bit of a bummer

A good arguement for keeping everything stock standard. lol :io:

Agreed, I have pulled off the manifold/tb a couple of times now.

Silicon should NEVER be used on ANY seal!

There is a special automotive sealant (aka Sikaflex) to use in these cases, and they should only be used to strengthen the seal on RUBBER gaskets only.

Just a prb i had - my car started to miss fire... i left it for around 3 months then it would choke cough, and turn off when i put a load on the engine - not to mention all the black smoke out of the exhaust... it turned out to be my COIL which is apparently "common problem" for the TH. I didnt think so but thats wat Mitsu mechanic told me.

Mate, get rid of the pod and put your clean or new paper filter back in, simple and will most likely fix your issue

oh mal... but then i loose the sexy intake noise i just got... bugger... well best go back to the standard thing/

ok, had split in both breather hoses off the rocker covers... so changed them... also changed fuel filter (after mal so kindly informed me of the part number)

idle is right now. still a very little miss on cruise so will put that down to the POD. tho with the pod i have build a can to completely cover it and direct the air in to if from a CAI.
after servicing my car should i have done an ECU reset?

update....

finding that the rear lead on the drivers side keeps popping off the plug after few days (unsure why this is happening)

took MAF off and cleaned it with a can of MAF cleaner (bit costly $24.95 a can)

cleaned all connection to MAF

ECU was reset (due to changing some wiring for stero gear)

still have pod on car is idling nice now and on throttle runs well. has a miss when driving at 2000rpm guessing i can put this down to Pod style filter?

hmmm lead is popping off the plug is not good! what is it like on 5cyls??

its the rear plug on the drivers side...if thats the 5th

Nah mate filter wont make your car miss...will just give it a different sound. Youve still got a problem somewhere...shoulda cleaned out the PCV while you were at it too:P

Pvc????

Just a point, my `99 LH Altera has always been abit bumpy on idle, now and then its good. It is serviced ontime, and I put a K&N Rampod for MAF sensor and It made no difference on the idle, nor created a miss. So no i wouldnt put it down to the POD, but the POD i have was designed apparently for magna and lancer with MAF. Anyway other then that i dont know shit :)

other then that i dont know shit :)

love it

its the rear plug on the drivers side...if thats the 5th

rear on the drivers side is cyl #2, is it not?
did anyone mention checking the dizzy cap and rotor?

It has been proven the round podfilter will upset the maf and cause it to miss, thats why k&n make a specific style for these cars.

yeah that too

I and a few others will disagree mate... I've had a 3" round, 4" round and a 6" round pod all with adaptors on the MAF and none made any difference to driving at all (besides uber awesome sound)

Ultimatly you want a pod thats bigger then the MAF area (I think 2.5" is a bit too small)

Yeah I can vouch for all my pods working perfectly (apart from hot air intake lol)

What I can suggest is you buy a proper MAF adaptor for them, as the supercheap ones block off several important holes in the MAF.

ok have found the issue. see the rear drivers side lead must have been cheating or something as the plug wants a divorce...

see i push the lead on the plug go for a drive runs nice for a while then starts to miss... stop pull over and the plug has spat out the lead... just comes off.. why the hell is this doing this... am i missing something really simple?

have you got a spare plug? test a spare plug in the lead off the vechile, see if it snaps in. if not well grab another lead from the wreckers

just brought the leads they are bloody costly for new ones to not work right..

guess i know what my saturday is gonna be

Have a few cans and get nice and toasted mate.

well wreckers first...then pull plug and lead out and make sure wanna stay together if not get replacment one or other.. after that mmm think a RUM will be needed... just the one... ha ha

with the pod filter, i think the distance between pod and maf dictates whether it will cause problems, ie too close to maf and will mess it up. the proper adapter would help i would think. i use to fit pods to all my cars but found they used more petrol. i did try leaving the snorkle off the diamante once and it made an awesome sound but seemed to lose low down torque.

rodssei i dont feel its my filter thats the issue... as if you read last couple of post i have put i have a spark plug lead that keeps poping off

I have had a thought - terrible if I am anywhere near the right track..... if the "popping" plug lead was on a spark plug that wasn't properly fitted in its thread, would escaping compression "blow" the plug insulator off the plug and the insulator up a bit out of the plug tube?

Be a real shame (being a rear cylinder) if this was the cause. I guess you'd hear a distinct odd noise from that area with the plug lead dislodged if this was the case. Or, with plug insulator dislodged and car cool, start car and can you feel any "breeze" from that plug tube?

Otherwise, could it be as simple as the metal contact in the insulator being a bit spread and not "grasping" the top of spark plug firmly enough, so that the rubber hasn't much resistance from "poppin" up off the plug? Or, was that insulator swollen at all, esp near the top (oil leak from plug seals can make the insulator swell and soften - this can make them hard to re-fit to plugs properly).

Just wild guesses about why the plug lead won't stay put - but should be easy/quick to diagnose and dismiss my suggestions as the biggest load of crap ever typed in the Forums. Good luck.

New leads can pop off, not sure about your theory, but they can pop off as the new silicone is rather slippery.

Had this happen, luckily it was on the outside of the rear bank. Half came off twice.

Also had it happen right across the rear bank, luckily the leads (1000km old) were shot anyway so off they came.

how do u make silicone non slippery.... bah.. wish it was the front leads.. so much less time to fix or play with

ok took tuffies idea went to wreckers and pinched a spare lead.. pulled car apart and chucked the lead on.. car seems to rum nice now with out missing and plug seems to like this lead... glad they are happy now

good to hear mate

how do u make silicone non slippery.... bah.. wish it was the front leads.. so much less time to fix or play with

I know its a late reply, but you cant make them non slippery - just sometimes they pop off, happened couple times to me - then I guess they settled in.

One reason that could make it worse is if you have oil around the lead.

mmm well old lead from wreckers seems to be working so aint gonna complaine..
