ok ive been running my car more now and i still have the check engine light on but it idles and runs ok. the only ques i have is just off idle it has a slight stumble. what could that be. ive put on a new IAC, and another TPS. both of which i believe i have set correctly. it still has a stumble off idle on acceleration. what else could it be? i was just gonna try a new 02 sensor. would that help? cars in signature below

Have you retreived your codes yet??? If you can't pull your codes by yourself why are you throwing money away??? Find out what your ECM is trying to tell you instead of guessing at it. Follow the link, look for the post by Vader, follow instructions and pull the codes:

Very simple to do. Give it a shot.

 

ok i finally got the scanner to work last night. i set the tps correctly and it showed a code 54. high or low fuel pump voltage. so i got a new fuel pump relay for it last night im gonna put it on today.
