Trying to track down a suspected vacuum leak, anyone got a vacuum diagram available? Google only showing radiator hose diagrams and wiring.
BTW, I say suspected because it's throwing p0171 and p0174 after CAI, Headers, and Tune. Pretty reputable tuner so I want to make sure there's no leaks before making the drive to see him again.
TIA

P0171 code is for Fuel Trim Bank 1 Lean
P0174 code is for Fuel Trim Bank 2 Lean

Considering you just had headers and a tune done, You are likely looking at an issue with your 02 Sensors.

I don't have the 6th gen vacuum diagrams unfortunately.

Exhaust leaks can do this too.
