I went in for a smog check on my 03, and it didnt pass. The guy told me that there really isnt anything wrong that the computer just "says" that the air to fuel ratio is not matched up. I have an injen cold air intake on it. He also said because of the intake that if I were to get a computer chip for it that that would make things right again. Any thought? What if I were to wrap a hand towl around the intake for a few miles until the engine light goes off? Would this restrick air flow enough to put the car closer to original air to fuel? At least until I get a passing inspection? Any help would be greatly appreciated.
