Code 41 is basicaly a " blanket code" it is a fuel control code and could signify a rich on lean condition, depending on whether you scan it koer, or koeo, which just mean key on engine off or key on engine running. It could be caused by an o2, or the map sensor or the fuel pressure regulator, ect. Your best bet would be to have it diagnose at a competent shop. It cost to much to guess at it.
