Default Help with clearing CEL

I have recently put new header downpipe and axelback exhaust on. Now i have a CEL. Im sure its from the 02 sensors. What do i need to clear the light? Also, could this car me to have a misfire in cylinder 4 5 6? I just replaced theplugs over the weekend... Any help is appreciated.

Worth the investment IMO. This will take care of your o2 sensors and pass you through emissions if you live in a state where it's required.

one goes through the firewall, under your carpet, connects to the o2 sensor plug under the passenger seat/carpet. the other one is in the engine bay.

and how does it work? you plug them in, and your done. no more CEL

I had the same miss fire issues. You may need to weld a new bung on the other side of the header so the motor can get a proper reading from both sides of the motor.

Yea tokensolutions is the best, I have one. Just plug it into your senors and go. Make sure you plug the shorter end up towards the front (I mistakenly plugged it into one near the throttle body, I dont know why the plugs where the same)
