    I don't have my diag stuff with me, but PO172 seems to be related to a too rich mixture (O2 sensor problem?), and PO238 seems to be related to the boost sensor wiring? (The boost sensor is the one mounted to the hardpipe between the intercooler and the throttle body (ETB)). Hopefully someone with diagnostics on-hand can chime in and confirm or correct

    More importantly, How are you reading codes??!! (Code reading/clearing without dealer software is the holy grail!!)

    Awww, Booooo!

    Is your check engine light on currently? How is the machine running? What RPM's do you reach at WOT?
