I posted this in the "Technical Discussion" board, but no replies. Thought I would check here to see if I can get some assistance.

Recently picked up a 2006 C2S, with the Carrera Power Kit (X51), and it has about 22,000 miles.

Car has been running fantastic, until the other day threw the check engine light. I ran a scan, using the Durametric, and below are the results that I'm most concerned about (There were a few others, which I'll try to address later).

I've done quite a bit of research, but basically I'm back to square one. I do have the service manuals, but am having trouble locating what exactly the issue is. Car is still running fine (to me), but would like to get these addressed before a bigger problem occurs. Any help or assistance would be greatly appreciated.

Note, I believe P0420 and P0430 are being thrown due to the Fabspeed aftermarket exhaust that is installed. I'm thinking that I can install some spacers for the O2 sensors to help alleviate this issue. Please advise if I'm correct.

The log of the codes is as follows: (P0660, P1043, P0420, P0430).

P1043 if i'm not mistaken. theres a solenoid valve to the right of the throttle body. make sure either its getting power, its connected , or working properly.
Hope its a start

 

P0660 this might be vacuum related. perform a vacuum leak check or look for broken loose vacuum lines
