Engine Mechanical problem
2000 Saturn SC1 4 cyl Two Wheel Drive Automatic 188000 miles
I have been working on a saturn sc-1 for a friend of mine. He has had transmission issues in the past, and a few minor engine related problems. The primary problem we are fighting now is the engine will not idle below 1400 RPM. I have a code reader which is giving me a code for IAC engine RPM too high, and Bank 1 too rich.
I have replaced the IAC valve and cleaned the throttle body. I have even replaced the throttle position sensor and one of the o2 sensors. Yet I still have a high idle. I have hunted for vacuum leaks, and even checked the egr system for proper operation.
Someone please help me. This is my friends only ride and I need to get it running right ASAP!
have the same problem?
