- P0171, p0172 bank 1 and 2 lean, p0324, p0326, p0331 knock sensor codes. Using scan data verified fuel system was running lean. Also noticed the throttle body was pulsing the throttle plate causing unstable idle. Found the air filter housing and intake air boot not properly installed and the hold down screws for the air box lid are all stripped out not holding down the air box lid. This was allowing air to bypass the mass air flow sensor causing a lean condition. Res exited the air tube and air box lid. Recommend replacing the air filter housing and the intake air tube between the housing and the engine soon.
