I know this can be a common occurrence with these things, but I wasn't able to find a thread on it to save my life. After working on some things this last weekend getting it ready to finally take possession, I noticed it to intermittently idle really high. Sometimes it starts up cold and idle at 800-900 just fine and other times it will start up and idle at 1,500. Then sometimes it can switch to the opposite of whatever it's at (i.e. 800 up to 1,500 or 1,500 down to 800) after it's been running for 15 minutes or more and up to temp.
So I know there is the Idle/Air Control Valve as well as the Idle Control Unit. Is there a way to tell which might be causing my problems based on my symptoms? Any way to test either of them? Thanks guys and sorry if I overlooked a previous thread on this.
