my cel came on during a trip after a long drive. its a rich code in both banks. my question is, when the cel comes on saying this, is this an extreme case of a bad a/f ratio? or is it just a small fluctuation?
Im starting to think our cars are very sensitive and the engine lights come on for very small reasons. All I have intake wise is a plenum and 75mm t/b with the stock airbox and my engine light is on saying Im running lean. I guess you could get a dyno to see how rich your running.
