So the high IAC counts (and poor idle) are only in reverse?
Your line of thinking makes sense--what happens in reverse to increase the engine load (or decrease RPM) that doesn't happen in Drive or neutral/park?
Grasping at straws, but could a bad motor mount cause this? Not sure if the engine tries to shift differently in reverse than in Drive. It seems like that would be more of a vibration than anything, unless some obscure wire is getting pinched.
How about an electrical short in the reverse lights circuit since the IAC counts are based on voltage, among other things.
What is your voltage in reverse?
An issue with the transmission position switch?
The ECT sensor is good, right?
