Trying to solve my high idle 1,000RPMs.Have cleaned the IACV. Ran the adjusting screw in, backed it out the same amount. Have set the TPS to .4 volts, the voltage goes up when throttle is engaged. Getting 5.1 out of the new harness. Idle is still high. I can bring it down to 750 by moving the TPS off the factory settings. While doing all this measuring and adjusting. I kept hearing a buzzing near the A/T. The buzzing only started when the throttle was held open. The Engine was not running. After all setting were made, the battery was disconnected for a hour.
