Can't get rid of CEL
I can't get rid of my CEL and it's pissin me off....I'm getting a code saying my car is running lean...I have replace both o2 sensors and cleared the code and it keeps comming back on...Only thing that is done to the car is a Vibrant header,Vibrant catted dp and vibrant 3'' exhaust... I have a new wideband and my car is running 14's at idle and while driving it's staying in the 14's-and low 15's while driving.....any suggestions

exhaust leak, if you have a leak at the header, could be letting air into the exhaust causing the code. Id check for an exhaust leak before the cat and about a foot after the downstream 02 sensor

The full exhaust on your car might have caused the fuel trims to go out of whack. I would guess you would know if you had an exhaust leak, so Im going to say get ahold of someone who can take a look at your tune and see if they can fix it or if thats what it is. To get the 0171/0172 (<--those are a guess out of my memory) dont your fuel trims need to be off by a lot, like 20%?
