CEL + TRAC OF light came on... HELP!
My check engine light and TRAC OFF light just came on my 2012 ISF. The codes I got are P0171, P0174, P1170, P1603, P1605. I have been running my Sikky headers with no problems for nearly 15k miles and am wondering what can be the problem. Under those codes I'm wondering if its my MAF sensor or just a simple o2 sensor gone bad on the pre-cat. Any help or input would be greatly appreciated!

I have also reset the light and within a matter of 20 miles it turned back on again. Also, my car is running like crap and the MPG average went from an average of 18-20 to 14-16 now since the light came on.

I had this problem when i first installed my Sikky headers. It was the O2 sensors. I had originally installed aftermarket sensors because there weren't any around at the time of this install. Once i put the OEM sensors in the problem went away. Check them first to rule them out. Good luck!
