Ok guys I have a problem. Changed the map no difference. It comes on within 5 seconds of the car running after reset. I also have cleaned the port going to the map. Checked operation of the map at computer as far as voltage. Everything normal. Cleaned Iacv. Was considering changing the Iacv but with there cost I want some more input before I do that and it doesnt help! Car is still idling at 1000rpms warm. Tested the ohms on Iacv and it is normal. Just wondering what the heck it could be. The car had a vfac or something to that affect on it at one time. Dont know if they store there info on the cars computers or not? Bought the car used has a aem cai and a 4 2 1 header. Gas mileage is down! Please help!!! Pulling my hair out at this point!!!

The scan tool indicates Diagnostic Trouble Code (DTC) P0108: A high voltage (low vacuum) problem in the Manifold Absolute Pressure (MAP) sensor.

Use this:


This is the proper procedure for troubleshooting your DTC.

if it had a vafc connected before, then someone must have not connected the map sensor wire at the ecu back up properly when they removed the vafc....double check your wires at the ecu make sure they line up to the right colors accordingly....start at the ecu and work your way out to the engine..
