Heres the video..

I am having off idle or de accel problems. If I rev the car up it will sputter and die when you let off only. It is also followed by smoke, not sure what color. There is a new HG it seems to be valve seals or turbo seals. This is a vid at ilde when I slowly let off and get it idling ok. Notice the light pop every couple seconds? I think thats part of the problem. How do u tell the difference between turbo seals and valve seals? the turbo is new. It never use to pop like that before.

i think you should take another vid. i hear the pop you are talking about but this vid doesnt really show the other problems you are having. my first thought when i watched it was that it seemed normal to me. just your exhaust noise. with 3in piping and no cats you are going to hear every little noise your engine makes, the pop might have been there before but you just couldnt hear it due to the stock exhaust. did you feel the shaft play on your turbo? valve stem seals will smoke on start up. ever check your timing? losing oil or coolant? what kind of condition are your plugs in?

 

[PorterzSupra]

I used this exhaust on my old motor never had that sound. The turbo is new no shaft play, timing is at 10 deg, not loosing coolant, plugs are new

It sounds like an intermittent misfire. Check your plug gaps, engine ground straps and make sure you didn't use Bosche plat plugs.

 

[PorterzSupra]

They are gaped to 28 thousands, engine is fully grounded, champion plugs

Lean misfire or a burnt valve would be my guess but hard to tell by a vid.

 

[mixmastermatt]

Definitely need to check your AFR. Either an overly rich or lean condition will cause that. I'm serious about you coming over and hooking the LM-1 up if you want. I have no problem helping you figure this out.

Check your spark plug wires for cuts, they could be arcing to a source on the engine.

Its what happend to me a 2 years ago.

Here is the NEW VID guys!!!! You can see its fine untill I rev it then when I let off it sputters and smokes then dies (sometimes it dont completely die) but then it suddenly blows clean again after its little fit and the revs go back up. WTF!!! HELP!! =(

Turbo seals?
Valve seals?
Could the TPS not know I let off the gas and is keeping the mixture rich? I just got a new one but I dont think its adjusted exact, my mechanic dident know how to do it after reading the TSM. If so what way would it need to be turned clockwise or cc? If I let off REALLY SLOW I can keep it running

Come on guys.. =( ^^^^^^^^^

On another note, sounds/looks like your AFM might be shot.

any codes being thrown?

[PorterzSupra]

AFM? I am running MAFT with the GM sensor, no codes it does it with the LEX AFM too

 

[Joel W.]

Follow these directions!!. Let us know what you do not understand and we will try and help?

 

[PorterzSupra]

untill the indicator deflects? what does this mean? I have a digital meter how would it deflect? Whats "Continuity" Thats what the mechanic couldent figure out either? I bought a set of thickness guages but I dont have a 0.70 in the set

 

[Joel W.]

From your other thread,
*Deflects just means it moves, So when the ohm meter needle goes from zero to not zero, it just deflected or moved. If you don't have a .050 feeler gauge, you can substitute a .020 and a .030 and put them together to make a .050 inch measurement. Or any combination that gives you the thickness you need.

*Continuity: This means that there is a continuous path for the flow of current in an electrical circuit.

Example: One wire has continuity at both ends until the wire is cut. Then the continuity is lost.

 

[PorterzSupra]

it does not say where to start the placement of the TPS, just as close to the middle as I can make it? Off to the left of right?? I think it starts off in the middle with like a .3 reading or somethin. So once the reading changes then back it off to the point where it was before it changed or leave it at the changed reading? I assume you think my engine is loading up possibly because of the TPS??

 

[Joel W.]

a digital meter has deflected when it is no longer at 0.0.
does your meter have an audible beep on the continuity setting? Maybe take a picture of you meter for us.

.3 is pretty much zero, so there would be no continuity at that location. keep turning it clockwise from there until the meter changes.

 

[PorterzSupra]

it starts out over 0 anyway if the TPS is in the middle position

 

[PorterzSupra]

Maybe im crazy but I dont see 0.70, or 0.30. It says were suppose to get 0.70

 

[Joel W.]

Umm ok, Goto radio shack and buy thier 24$ digital meter #22-802 It has a speaker that beeps when continuity is made on the CONT. setting. Move the tps all the was counter clockwise, hook up the meter on the E2 and IDL prongs of the tps and put your feeler gauge in throttle stop screw, Now turn the tps clockwise until it beeps and tighten the screws.

What sizes does it list on the feeler gauge?
