- Both banks rich. Found alcohol content at 53% and fuel trims at -22% relearn alcohol content and reset fuel trims. Long terms at -7 -8% now. Replaced air filter 22487 and cleaned mas air flow. Reason for doing so is the fuel trims went back to -15% after test drive and idling for a few minutes after. After cleaning MAF and replacing air filter. Fuel trims are down to -5 -7 Now after test drive the fuel trims are down to -3-5 and dropping. Customer will need to drive it maybe 2 tank fills to see if light comes back but as of right now all is fine
