Computer problem
1993 Buick Century 6 cyl Front Wheel Drive Automatic 50,000 miles

I have hopefully narrowed the problem down the the idle motor. I have been looking for the ecm harness ground with no success. Any help?

What you have is not a an idle motor-its called idle air control valve-check for foreign material in the IACV bore that might causing your rough idle -if this the case-

Inspect and test the throttle position sensor
