My new pick up/ holy shit problems TT

[2faststealth4u]

Okay so today I traded my Lexus for this
5774
5775
5776
Now I think and so do a few others that it has a wiring issues
Spews smoke on cold start laced heavily with fuel
Not Hg or anything just straight gas.. Stutters and hesitates after VAC. And some times the ecs bugs out and when it does the oil pump and everything else does as well.. The old owner says ecu replaced.. But I have no clue I'm stuck don't see any signs of boost leak checked all the lines.. The turbos have a small seapage leak that burns off if u let them sit to long.. No oil in lines to y pipe.. Plugs and wires check out and no smoke after a while.. Tomorrow I dig into it :) I'm glad to be an owner again

[FluffyCow]

Unplug that ecs comp asap. It can screw with everything if it's bad

Yeah I was thinking that but it was functioning?

Insides clean

[FluffyCow]

You said it bugs out. You don't want it taking out any other electronics

Get the ECU out and inspect it cor leaky caps. Tell us the numbers on the ECU.

Maybe the previous owner put the wrong one in? Or Even if it is a new ECU, it could be bad also.

[2fnloud]

The oil pump bugs out? I thought that the oil pump was mechanical? Why do you think that the oil pump is "bugging out"?

[2faststealth4u]

Functioning properly when everything else is.. But when everything else is goin crazy the oil pressure goes up and down as u hold the rpms.. :/ ill pull ecu in a bit

[2faststealth4u]

Starts to dig into it an bam rain.. Guess time to clean the garage

[2faststealth4u]

See now its fine video to follow soon

That idle is awfully high. I'd check the iac as well.

[2faststealth4u]

It idles down after it warms up.. I'm about to pull the ECM.. If its bad I shoul probably just buy a chrome right? I mean it's plug and play so idk :/

Not at cold idle...

[2faststealth4u]

Pics of ECM it does not look right to me I maybe wrong here

5780

[2faststealth4u]

5784
Some of the chips are bent idk :/ looks dirty and nasty

[FluffyCow]

Whoops. Dumbass me switched engine temp and oil pressure in my head. Lol... Fwiw my car doesn't idle that high when cold. Odd. My iac works cuz it holds idle right were it belongs with the AC on.. I think.

What does your car idle at once warm. My car idles right about 1300 cold and 700/750 warm.

I would unplug the ECS computer and drive it around to see if it still "bugs out". The ECS computers are known to also crap out.

So check the strut wires/caps.

[FluffyCow]

First thing I suggested to him was unplugging the ECS comp. Don't know if he has, or why/why not.

Lol I'm working imbetween rain and yard work and car lol

[2faststealth4u]

That and I know how to pull the motor but never dc ecs before :p

[2faststealth4u]

Dc from the trunk right?

[2faststealth4u]

Yeah I tried and same stuff still drove like crap bucking and stuttering under boost exhaust smells like gas big time not as much smoke.. :/

[FluffyCow]

Ecu. Personally I'd get a chromed ecu.

Boost leak?

[FluffyCow]

True. Thought you tested though

[2faststealth4u]

Tightened everything I'm thinking of pulling the side mounts and inspecting them

[dbest671]

Have you actually pressure tested? A pressure test would tell you if the side mounts are leaking versus actually pulling them.

Stealth twin Turbo VR4 smoke on start - YouTube (http://www.youtube.com/watch?v=yuP2Dzt2WO4&feature=youtu.be)

here is the vid from this morning sorry for the delay

[2faststealth4u]

Any one?

[2fnloud]

From what I can hear it sounds like it is idling just fine. The smoke could even be from leaking valve guides.

Yeah but it's only fuel

[2faststealth4u]

Oil change is done mobile 1 since i didn't know wither Rotilla T6 is safe but now I do.

Also let it site after draining and the oil separated and u could not only smell the gas but see it ontop of the oil. Friends coming over today to see what he can find

[2faststealth4u]

Sit•

[B-Man]

Are your o2s fluctuating at Idle? Stock injectors? Coolant temps reading reasonably? I'm surprised nobody has said this, yet, but that looks awfully white to be just fuel.

[2faststealth4u]

Coolant and coolant temps perfect, and as for the o2 how do I tell? I have no codes. I bought some ngks I'm going to replace the plugs as well but honestly I'm stumped.

Use a palm/scanmaster.

[2faststealth4u]

Use a palm/scanmaster.

Okay my friend is brining one and a volt meter to check for a short in the injector harness. Then if nothing next step is plugs, maf and so on

[B-Man]

You do know the ECU uses a separate coolant temp sender than the gauge, don't you?

[2faststealth4u]

Yes
Also there is no mixing of fluids. And the white ish smoke if u hold ur hand up to it and smell its pure I mean pure gas.. Probably light on fire if u lit a match.. And as for the stumbling I might not be burning the fuel from a cylinder so it's causing it to just dumb? It's miss firing and every thing :/ thanks for the help so far

[B-Man]

You can still burn coolant without it getting into the oil, but if your levels are never low, maybe it is just fuel. I've just never seen it white like that.

If it's only on cold startup, it won't be the o2s since they're out of the loop during open loop operation. It's not a rule, but all ECUs I've had go bad have caused spark issues, not fuel.

Have you checked your timing? If you're off just one tooth it can run fine at low loads, and cause issue at higher loads. I'd also check your MAF reading at idle. I usually see ~80Hz cold and 50-55Hz warm idle.

[2faststealth4u]

It's only during cold start

[2faststealth4u]

And will do thanks

[2faststealth4u]

Stopped raining so ill let u know what I find

So idk

[2faststealth4u]

Taking injectors to get tested.. Heavy fuel sat on plugs and I have an exhaust leak and when I start the whole inside of the car smells of gas as well

[PearlWhiteR/T]

As another member mentioned. Make sure timing is correct. When I first got my car the timing belt had just been done, but not properly. It was off by 2-3 teeth on the front bank and 1 on the back I believe. On the verge of bending valves I'm sure, but it didn't. Caused similar issues to what your describing though. My car ran pig rich, wouldn't rev past 5k and would buck terrible especially on decel. I would go that route myself first before checking other stuff. Anyways hope this helps man.

Thanks ill double check that tomorrow :) car only has 78k and I have all dealer maint up to 72k.. May have sat to long PO stated that he got it running and drove it then parked it over the winter and this issue came up.. Still a lot can happen in that 6k.. I'm thinking about just replacing my injectors while I'm in there with DSM ones :). I did this 2 hours ago and can still smell gas from behind the car..

[2faststealth4u]

No news on the injectors yet :/ I just need my car running wish more people were local.. No 3s gurus out here that I can trust

[2faststealth4u]

Uhoh

[2faststealth4u]

So I just read a whole thread on this from a mitsu forum
Some one had exact same symptoms
Diagnosis
Fuel pump over pressure
Cause
Fpr failure
Cause
Injectors to constantly spray fuel
Cause
Injector failure
Effect
Lurching stumbling
Smoke from exhaust heavy fuel smell
Plugs fail

Hmm so
Safc injectors and pressure test the system

[Streamln1]

Your running rich, it could very well likely just be a pressure leak. If your air meter is sucking in more air than the engine is actually getting, its gonna run rich, and there are about 1.5 million places the air could be leaking on these cars.

Just do a pressure test before complicating it further, then move on to other diagnosis

Secondly, replace plug wires and plugs, espeically if high mileage, its something that needs done anyways

Thanks I will :)
And plugs wires brand new now car only has 78k ^_~

[Streamln1]

Sounds like a boost leak or a bad maf.

[dbest671]

We've asked and told him to pressure test a few times now... why he hasn't is beyond me. That's the first thing I do if I have any issues like he has. Hell, it's the first thing I do after messing around in the engine and having to take vacuum tubes off (like when you remove the plenum).

[Hard AttacK]

What are your mods? Have you even tried unplugging your ecs computer yet? Takes 3 minutes.

[PearlWhiteR/T]

What would disconnecting your ECS computer do relating to running rich? Two totally separate systems... Are they not?

Because a bad ECS computer can cause issues with the ECU... and make it do weird things.
