My car listed above has been having problems related to the engine running rich. It used to be misfiring and was fixed with multiple sets of new injectors and spark plugs. Yet the engine is still running rich and idling roughly. We have replaced almost everything to do with the fuel line and system, evap solenoids, every rubber tubing piece, new intake gasket, cleaned throttle body, new O2 heater unit sensors twice, new MAS, ran a smoke system through the engine and found no leaks, replaced PVC valves and cleaned/ inspected every inch of the engine. I am curious if it has to do with the ECU and ECM systems or any voltage issues.
Any ideas to what the issue could be related to?
Thank you.
