Supercup exhaust issue
My 99 Boxster came with the Fabspeed Supercup exhaust and apparently does not have cats. 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. |
Try putting a spark plug non-fouler in between the O2 sensors and the pipe.

Not having Cats is not going to have an effect on that sensor. Not having Cats is not causing that code. The other two codes are for your Post cat sensors. |
