    Hello Forum,

    GP is throwing codes again. It all started with a bad gas cap that wouldnt close, bought a new one, gas cap is good.

    The Codes:
    P0172 System Too Rich(Bank 1)
    P0401 Insufficient EGR Flow
    P1811 Max Adapt and Long Shift

    I have cleaned the MAF, inspected for vacuum leaks with Carb Cleaner, cleared the codes and now I get P0172 again.

    Any suggestions?
