And here is the biggy!

I have sent 50 or more wiring harnesses to the dealer with under 120K and all were done for FREE! (RBM of Atlanta)

Also, I have replaced several of the throttle actuators and all have repaired the bad idle/ stalling complaints. I have NEVER had to replace the control unit! I could see this ONLY if the throttle actuator is faulty and it BLEW out the controller. So if you replace the controller without the actuator, well it will blow too.

Have your mechanic GENTLY slice open the throttle actuator harness and look for broken wires. I'd start there.
