Code P080, Fuel System Rich: Actions

WARNING: This page is about a different car, the 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

PCM turns on MIL. A rich fuel injection system can be caused by leaky injector, faulty fuel pressure regulator or restricted fuel line. A continuous evaporative emission control canister purge can be caused by a leaking EVAP purge valve, purge valve solenoid, circuit or PCM.
