    Po172 & Po174 Fixed 2001 Dts

    P0172 - Fuel Trim System Rich Bank 1
    P0174 - Fuel Trim System Lean Bank 2
    Well I took it in this morning to my service shop and they removed the intake and replaced the plemun that connects to the bracket on the drivers side of the engine.
    The bottom of the plemun was torn. I just wonder how long this has been this way before it tripped the code?
    Well $172.00 later all is well again.
    It has 118,092 when this was replaced.

    Well everyone have a Happy Easter.
