I have had this problem for 3 or so months and it just wont go away.

I have the following mods, Extractors, full exhaust and a Pod. As soon as I got the full exhaust (only had a muffler at the time) the car struggled. The car barely took off and almost stalls, but as soon as I put my foot down it's fine. I took it to Mitsubishi and they replaced the oxy sensor and bypassed the fuel pressure regulator.It was fine for a while, only very occasionally it happened.

When In Melbourne Mal thought it was strange the way Mitsubishi had tried to fix my car, And then while at an exhaust shop and Ex Mitsu Tech was confused by what they did. He suggested putting the blocked up line back on and resetting the computer.

The struggling came back when we cleaned the pod, really bad. I decided to replace the pod with the stock airbox and filter and try.

Still the same problem but now the engine sounded different, Like a ticking noise. I reversed what Mitsubishi done and reset the computer, kept it at 2000rpm for a while but it was still ticking, A little more now. I'm very confused by this and I'm not keen on taking my car back to the Mitsi dealer again.

Any Idea's?

Wouldn't be a cracked gasket somewhere? I had a ticking coming from my engine and it ended up being a cracked gasket. And it was air that was making the noise, from compression or decompression I believe it was.

Also I am not sure what you really think the problem stemmed from, at first you mentioned it was after the exhaust was fitted. is it possible that there is no or a lack of back pressure? I know when I had my Redback installed they recommended fitting a 'Z' type exhaust which increased back pressure.

Do you think you might have 2 problems?

I know the difference of sounds of a cracket gasket, I've replaced a few. And Back pressure has been suggested to me.

I believe Mitsi tested back pressure, and said It's fuel But I dont understand, It was right after I got my exhaust, I may call my exhaust shop tomorrow.

Can the cat do horrible things to performance if it is on the go?

I didnt replace the Cat when I got the system, Hrm.

tappets?

cos when my tappets died they sounded horrible at low rpm, but put your foot down and the sound dissapeared.

The ticking sound that only started today doesnt seem to die when I put my foot down.

what size exhast/muffler etc?

Trav

2 1/2" Muffler and Exhaust.

Sounds like an exhaust gasket somewhere.. I would say the leak is affecting the readings from the sensor on the the exhaust (maybe) causing the computer to feed the wrong amounts of fuel into your engine...

make sure ur oil level is right, it could be airflow sensor, did the car ever backfire? (sounds like ur knocking on the guard with ur knuckles)

I know when i got my extractors fitted the oxy sensor died (caused by using too much sealant and probably being exsposed) that in turn caused my car to backfire which then killed my air flow.

My car was doing something similar to ur which was accelerating and almost dieing, but then u put the foot down and it was alright.

If you haven't replaced your cat then thats something worth looking into. If your cat is dead they basically crumble and block up, which can restrict exhaust flow badly. Its a simple job to check, just unbolt it and ensure the honey comb is in good condition and that its not rattling.

High flow items aren't too expensive either, around the 220 mark.

I had a ticking sound that was almost identical to tappets with my old extractors when they were cracked...something to check maybe?

I had similar problem a couple of times. Firstly it was the headers had a crack ( just a little one) but in a few pipes both front and rear bank. Had them tig welded up and no more probs for a while. Then the ticking came back, thought **** not again. Got in and checked and all it was was the nuts to the headers had worked themselves a little loose. So a little elbow grease and they are fine and no sound. All better and i check them once a week now.

Yeah I'm pretty sure it's got something todo with the exhaust, But not too much on the extractors because I was at the exhaust place last week and got a new gasket, If there were other problems on the extractors I'd think they'd notice.

What confused me is that the mitsubishi bypassed the fuel reg for a higher psi and the problem basically went away, but if it was an exhaust problem wouldnt the problem not diminish with extra fuel?

Also, I only have 1 muffler along the whole exhaust, and thats at the end. Could this be a factor?

is the exhaust loud inside the cabin?
it was pretty loud driving behind ya at MM04

Not really, pretty quiet compared to some Magna's in SA. Bit droney sometimes.

it wouldnt be something like a clogged fuel filter? i dunno why they would bypass the pressure reg sounds like theyre just avoiding the problem rather than fixing it..
bypassing fuel pressure reg fixes it - wouldnt that mean low fuel pressure, or a faulty reg?
dirty filter / bad pump?

So many different things aye, Graham West are looking at it today, see what happens.

Well I found the problem, the valve in the 6th cylinder is not opening properly, That means I need 2000 to fix. Heh.

sif all u need is a hammer and duct tape

Bugger!! You can get a new 3.0 for over 3000 aparently... PM funky fresian cows to double check.

Not alot of point of a new one since what work I want todo replaces many bits. Ill try and source a new one or some other form of engine transplant.

Tyson i dont know if u remember but Mal said something about i running on 5 cylinders, geez he was perty close.

ps he was a god send on mm04

Yeah I mentioned that to Karen today. Time togo shopping for transplants.

ooooo will a DOHC fit?, if it does as far as im concerned the choice for a transplant has been made. DO IT!

thats not a new engine.

thats a new valve spring ~200$ + labour
or
a new 3.0L Head ~500$ + labour
worse case
a new 3.0L head and new pistion for cyl #6 ~650$ +labour

:doubt:

yeah i dont get why u would have to get whole new engine tyson

get a new head and do some mild work to it

then u will fix 2 problems.....heavy right foot and also broken car

Labour makes it out to be 2000, I guess while the engine is in pieces I could stick new bits in. But hrm..like what?

Honestly I think your best bet would be to rebuild your heads, do a mild port n polish while there out, replace the valves and put in heavy duty springs. Put in a new set of cams and then your off n racing. This is only feasible providing the rest of the engine is in decent condition.

119,000 clicks, It's still a baby

Then definatly rebuild the heads, port n polish, upgrade the valve springs and plop a new cam in. Go stage 2 cams if you have a piggy back computer coz now your heads will be able to take it.

That 3L would go hard then :D

In the words of hutch "do it"

the engine doesnt need to come out tyson...you can take the heads of yourself and send em to a performance/reconditioner and/or exchange for rpw unit

piss easy mate

4Pleazn said a bad word!! :hand: :silenced:

Give me a call Tyson.. ill sort you out :fruitcake

poor diddums

dont let booya sort u out...you know what he does to his farm animals

you will start ya car up and chicken feathers will come out of the exhaust :nuts:

that was your mummas wig that came out my exhaust that time dave..
lol

not chicken feathers :badgrin:

rumour had it that it was YOUR mums bum fluff

ooohhh k guys ease up lol

sorry blake...i apologise on behalf of booya and his stupidity :gtfo:

sorry blake

now :gtfo: fooya.. haha

Fit a MIVEC.

OS 3L TT :redface:

Fit a MIVEC.

I've thought about that, and maybe a manual conversion. I'll get quotes on every option and see what works out best

Japanese Auto Spares 07 5593 6888
Burleigh Heads in Surfers.

I was in there in July with my Bro chasing 300ZX twin turbo parts. They had several Z32 front cuts at reasonable prices. Low and behold they also had several FTO and 3000GT engines (3.0L MIVEC) with wiring looms and ECU. Seem to recall one even having a gear box (manual) for a conversion.

Mitsi Spares in WIngfield apprently has Mivec's

3000GT engines (3.0L MIVEC) with wiring looms and ECU
GTO / 3000GT's don't have Mivec engines.

There's a Just Mitsy place with a Mivec down at Labrador. He want's to see up so it might be possible to get it cheaper than what he's asking for the front cut, ($3500).

I believe he still has the GDI donk also Redav? is this correct?>

yer he has the gdi and the mivec stil there

he kinda wants to get rid of them so ive been told by the other workers there that they reakon he would accept a whole lot less

I didn't think the Mivec looked that crash hot. I get a bit worried with engines sitting on the coast with the salt content in the air. It may only be surface stuff but I just wonder how the other rotating parts handle it.

But this made me feel like an expert :redface: It's official I know nothing about cars :cool:
I stand by the fact that there were several mivecs at this place regardless of what they came out of :thumbsup:

I don't know bout you, but I don't consider 5-10km from the coast to be "coastal". I certainly don't get a "seabreeze" where I am (about 2 minutes from that Just Mitsy place.)

You were close :D

Well, it was close enough for me. Mind you, the pitted metal could have occured while sitting in Japan.

The sohc engine is boring, a Mivec would be very different and for 3500 you cant go wrong.

True but will you be able to pull the conversion off?

I like to pull off things.

I'll source quotes during the week and see what ends up better, and by febuary I should be able to go through with it, I'm sick of having to restart my car when I reverse out of the driveway, It loves to stall

LOL ROFLMAO ! :badgrin:

Bro you sourced a mivec for $3500. WHEREABOUTS my engines done 180k and i was thinking of either doing a full rebuild with bits or trying to get my hands on a mivec. I was also looking at a galant 2.5L V6 TT but no go

i know of a couple of these half cuts up here at gold coast

I may be getting repairs for alot cheaper now, So I'll prolly stick with what I got and add a few bits.

But what model are you running ( would it bolt straight into a TF 3.0L 98 model )
