So I checked my IAC due to the fact of my truck not starting below 70 degrees and found it to be bad. Used the trusty unplug it while it's running and nothing changed. My question now is, is there any way to test just the IAC or just the connection? I don't have $50 to fork out for the IAC and the connection is much cheaper. I pulled it off and found it still moves regardless of the filth in it but I know this is my problem just unsure which part of it.
