Well I tried the tps and nothing so My buddy with a Lightning swapped IAC parts and nothing it still idles high when You unplug the IAC zero happens could a fuse be blown or how can I check to see if its getting proper voltage?? I hope Someone knows cuz on Monday I have to take it to Ford time to pay out the ****.

 

Yep. His IAC isn't getting a signal. If you plug or unplug the electrical connector the idle does'nt change. Tried this with a known good one, mine, same result. Anybody else seen this problem?
