What I did was clean the MAF sensor and the Throttle body . ( there are several kits available with both spray cans ) That put the lights and the codes to rest for me . I had blown the engine and filled the exhaust with oil so I ran (several times) bottles of catalytic converter cleaner (one per tank full) thru before I used the spray cans to clean the MAF and TB . This is much cheaper than a new cat.converter .
