I have a HKS intake and I get a check engine light. Now before I start, I have OBDII tested and get twice MAF sensor failure. Is it do to the intake(which a few has said) or the MAF bad? Someone also said to check if it is the intake to unplug the ECU for 15 minutes to reset it, would that test really work? I don't mind replacing the MAF, but would like to try other things before I spend the money. By the way, I am getting real $h!tty gas mileage.
