    p2135, po120, po220

    I'm getting these codes on a 05 Chevy silverado, we did a nnbs intake swap a while back and just recently it started acting up and threw out these codes, it has a rough idle and dies all of a sudden. The truck is cammed, sorry I don't have any logs of it. It is tuned by someone else, anybody ever had this problem? Any ideas that might help to diagnose what is going on?
    Thanks, Roger

    Sounds like a TB issue.
    Check connections and have also seen the wires break in the insulation near the TB itself
