trance42 Posted May 17, 2006 Report Share Posted May 17, 2006 I cant figure out whats going on. When i drive normally i have no problem. As soon as i go over 5-10 bs of boost i get this studder. The boost stays where it is. I have 750 cc injectors and garett turbo. I am not tuned yet but i hav not had this problem yet. i have been driving The car since christmas. I pulled codes. some i can find info for others i have no clue what they are. 335543455454542231453452214I know what 335 231 and 214 are. the 231 is because im running rich. 335 manual swap. 214 possible bad rpm sensorDoes anyone know what theese other codes are?I would apriciate any thoughts that anyone might have on this.Tim Link to comment Share on other sites More sharing options...
jediboytj Posted May 17, 2006 Report Share Posted May 17, 2006 higher octane fuel maybe? that fixed my stutter/hesitation on full boost in higher RPMs. :unsure: Link to comment Share on other sites More sharing options...
grocerygetter Posted May 17, 2006 Report Share Posted May 17, 2006 Have you changed plugs recently? Try that, if you are running rich they tend to foul quicker. Link to comment Share on other sites More sharing options...

Sean Posted May 17, 2006 Report Share Posted May 17, 2006 Does doubling your injectors size like that kill your gas milage? Link to comment Share on other sites More sharing options...
trance42 Posted May 17, 2006 Author Report Share Posted May 17, 2006 Thanks for the good info Rob.The emissions is because of having a 97 motor in a 95 car.It doesnt really worry me.On the other hand these worry me. -Crankshaft Position Sensor A Circuit Malfunction -Fuel Pump Secondary Circuit Low -Cold Start Injector 2 MalfunctionAny one else had these probems before? No the injectors do not cause bad gas milage? they are saturated injectors so as long as im not flooring it im geting around 18-20 in the city. i did over 400 miles on one tank of gas on the interstate.
