It is throwing emission CEL's (P1132, P1117, P0140) I did research and know that these are related to o2 sensor. Since my car doesn't have cats am I doomed to having to clear the CEL's every time? My understanding is that the 2.5l H6 is cable driven so I can't flash the ECU? Just trying to understand my car- runs great just hate it when the CEL pops up on a spirited drive makes me nervous.
