Engine Performance problem
1993 Chevy Lumina 6 cyl Front Wheel Drive Automatic 143000 miles
I recently moved from 6000 feet elevation to sea level. My car ran fine for about two weeks, then suddenly lost power. I tested for spark on cylinders 2, 4, and 6 (the front three), and discovered there was no spark on cylinder 4. I swapped the plug and wire with no effect, so I replaced that coil. My next guess is the Ignition Control Module. Is there any way to test it before I replace it? Any other suggestions?
have the same problem?
