Engine Performance problem
1987 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic

I pulled codes from my car using an code reader. The code I got was "rich exhaust indicated (left side dual oxygen modules)" and the other code was "Electronic spark timing (EST) circuit - low voltage detected. Electronic spark control (ESC) - circuit problems. WHAT DOES THAT MEAN? WHAT DO I FIX?

Do you
have the same problem?
Yes
No
