Question about 2001 Chevrolet Silverado 1500
I have a 2001 silverado 4.8 and it is giving me a lean code on bank 1 & bank 2. I replaced the intake gaskets and the fuel pressure regulator. I've replaced all four oxygen sensors and i have a K&N filter on it. I've cleaned the map sensor, maf, and the throttle body, nothing. What could cause this?
Vacuum leek,bad computer or you have a linkage out of adjustment on the throttle body
