I always noticed my sonic ran slightly richer stock, put a cold air on it it runs totally lean high + numbers gray spark plugs. Stock air box - numbers never had codes with these except the lean one p1101 take off the cold air goes away. This was even after the boost sensor, maf, inter cooler...
Came up with a P2227 barometric pressure circuit code wanted to try just replacing the mass air flow sensor anyone have any suggestions that have come across the issue before.
