First Post....09TL Help!
I have an 09 Acura TL and I put a K and N cold air intake on the car. It immediately threw lean codes (P0171 and P0174) and I have taken it to 2 shops and they can't tell me why. My gas milage has gone from 33 mpg hwy to 24 mpg hwy. One shop told me it is the computer shoting more gas in the mix to optimize the mix. Is there a way to get the computer to compesate for the cold air intake? I really need to get my MPGs back up.
Thx for the help!
