    Does the car start?

    Are you able to read the pcm?

    Are you able to write to the pcm?

    Are you able to scan the vehicle?
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Only the P codes are valid when scanning with Hp Tuners. The P0128 is set if the ECT stays below 172*F.
    Did you install a cooler thermostat? If so, you need to disable the code.

    Like I said before, only the P code is valid.
