I had an IAT related code. Did all of the troubleshooting and it pointed to replacing the IAT. New IAT did not solve the problem...

I went back to re-do the troubleshooting procedure, and I finally noticed that there was a mostly broken wire right at the IAT plug. This connection gets a pretty hard kink - may want to look there. Otherwise you will need to ohm out the wires from IAT to PCM to see if there is another wiring issue.
