Ok so WTF???!!!!! Am i Doing something wrong? Everytime i put in an aftermarket Intake My check Engine light comes on with code P0171 (Bank 1, System Too Lean) Did anybody have this problem with the AIR INTAKE?? Im thinking that there is not proper mixture so it could eather be bad fuel injectors, or need to change the Fuel FIlter, Or maybe the teh MAFS is defective..... BUT WHY THIS ONLY HAPPENS WITH THE AFTERMARKET INTAKE????? When i put the regular intake the code desapears...Ive been swtiching back and forth for the last 4 weeks.. Guys i really want to know what you guys think????
