[QUOTE="Roush6018, post: 16792962, member: 78571"] yes i have an idea on your problem. i think you can find the problem. the dash wire does not have anything to do with your check engine light. i think your problem is fuel injector related. use a stethascope to listen to all 8 fuel injectors at idle, verify they are working by listening to them one by one. you should hear a tapping or knocking noise on each fuel injector. if you find one that isn't working it will be making no noise at all. also i want to ask how is the car running and driving ? does it run great ? does it run bad ? does it stall out at a stop sign or stall when it is hot ? does this vehicle have an exhaust leak anywhere? the computer is working ok because it is using the O2 sensors (and the MAF data ) to determine the lean condition in the exhaust gasses. , then set the codes (with freeze frame data ) and turn on the check engine light.
