I have an LMS CAI and it is giving me a check engine light. I got the car diagnosed and it turns out that my car is running too lean. How do I fix this?
i got a tune up about a month ago when i put in the torque master plugs but i dont think that should be causing me to run lean. if i do get an safc, wouldnt the ecu readjust itself to the piggyback system and throw a check engine again? also, is it ok for me to drive around with the engine light on until i get it fixed?
