Hey everyone was wondering if you could help me out? I am working on my buddies 96 Sunfire w/2.4 it wouldn't pass emmissions cause it was running to rich on bank 1. Check Engine light has been on for a really long time, I took it to have the codes ran on it and I ended up replacing the following parts, Cam Sensor, Crank Sensor, O2 sensor pre-cat, fuel filter, air filter. After replacing the sensors the Check engine light still came on and also this is the thing that is bugging me when the car is idling at 1K at a light or whatever and you give it some throttle the rpm's drop down and wants to die initially. Sometimes when you are turning into a corner and you down@!#$ it will die completely. Was wondering if anyone has any ideas for me. TPS maybe?
