Whenever I put an aftermarket cold air intake on my 2009 se 2 door coupe 5spd manual my check engine light came on, it went into closed loop, so my fuel mileage went down. I want to know if anyone is running some kind of programmer or any kind of tune to help with this issue.
Or just want to know what programmer if any that y'all have.
