1994 Chevrolet CORVETTE, CKP Sensor, CMP Sensor Scandata
Posted to the Waveform Library on 1/14/1999

This vehicle has a ver erratic idle as you can see in the snapshot above. The PCM interpets engine RPM erratically and then outputs erratic spark and fuel commands. I believe that this problem may be caused by a defective "Optispark Distributor"
