Friend who installed sikky headers a while back is now having CEL popping up always. Any idea why? Bad extensions or something? Where can i get a replacement from? Thanks

Either he needs new o2 sensors, or they didn't install his microprocessor right..

Since the car was running OK for thousands of miles im guessing install was right. What is included with the headers to prevent cels? I know ppe included conditioners with their headers. Thanks

I got a O2 CEL on my F and it ended up that one of the wires on my PPE conditioner came loose. Not sure if the Sikky headers come with electronic conditioners, if they do, check the wiring.

Having problems too but idk if it's header related getting codes saying running to lean in bank 1 and 2
