i have a megan header, s pipe, and custom cat back exhaust. i got the cel, installed the anti fouler, went away. month later,(today) it poped up agaain....not forsure what happened or what to do.....should i put another one on, and what about putting one on the header, i heard of this being a last resort for the problem...help!!!

 

reset it again. it should fix it.

 

Do not put a anti fouler on the header a/f sensor. Go get the code read at autozone to make sure everything is good. Rule of thumb is if it stays off for 250 miles then comes back then it may be a different problem.

 

Exactly. I think people truely forget that it means CHECK ENGINE.
