Just picked up a new rig, and she's throwing a light...here's what I got....

P0101- MAF Sensor Circuit
P0171 - Bank 1 Lean
P???? - Bank 2 Lean, lost the paper from VatoZone
P0332 - Knock Sensor 2 Circuit low input bank 2

04 Crew, stock as far as I can tell....no noticeable misfire.

After this scan, i had the codes cleared, came right back, took it home.

Put on my K&N element from my old ride, cleaned and reoiled, hit the MAF with some contact cleaner, and reinstalled...still got a code.

all connections are secure as far as I can tell (less knock sensor...don't know where that one is at)

Any help is much appreciated...this light is driving me insane.

 

bump...
