    Will do. Battery cable is off. Will check it tomorrow and report my findings. Software is really buggy. IAC readings disappeared again and wont come back.

      There's 2 kinds of IAC valves. The 4 wire unit on the XT manifolds ( stepper motor ), and the 2 wire unit used on the rest ( PWM ). Both are driven differently. So you need a specific ECU for each one. I believe it was Pro-Flo 3 where they fixed, where people were installing the wrong software for the type of IAC valve....it might be where part of the bug is.

      Anyway:
      You might want to check the IAC valve. This link might help: https://www.chevytalk.org/fusionbb/s...hp?tid/270988/
