Are you running bigger injectors on a stock ECU with no way to control them?
No FPR?

If so - the ECU cant adjust them properly (lean or rich) so its tossing the code.
If NOT - you've probably got a stuck injector.

its a stock Ecu eprom with a stock chip in it and stock injectors.


ill run some injector cleaner in the next fuel up and hope it will help out . its running perfectly fine thats why it threw me off !

thank you so much for the info .

I can't find much about p0170, but it seems that it might be caused by a few leaks in the intake system, either pre turbo or after.

Also, get that throttle stop thing fixed, as per what we talked about, and set that TPS so your engine knows its at idle when it is.

Remember, 1995 is an EARLY version of OBD2, so its a bit wierd.  Odd things can happen and even with newer cars odd things will cause codes that at first don't appear related.

 i fixed the throttle  stop screw thing the next day after we talk , no more  gas pedal getting stuck and i dont look like a tool reving my engine everytime to get it unstuck befor leting the  clutch go . LOL
 i drove it arround  and it seams like the engine check ligth is not  coming back on and have been pushing  her  hard .

got some injector cleaner and some good 94 fuel  ill see how it runs after this tank.

did you set the TPS?

[Constantin Morosan]

did you set the TPS?

yes i did ..  set it  in the middle like u asked me too do  .. anything else that i could do ? maybe crank it all the way to the other side see if it helps .. since its still idling wierd .

well, I said to put it in the middle as a guestimate on where it should be simply because it was all the way one way    Set it with a volt meter.  0.48-0.52 volts engine off, key on.
