I put a new IAC motor in my 2001 cargo van 3.9 BUTTT
I can't get the pintle to move in and out. I bought a new air motor control to no evail. I just don't understand why it isn't going in and out.
Remember I am an ignorant wanna be fixer. I have had it work sometimes but 99% of the time it doesn't work which creates to much air and bad reaction to the gas pedal being pushed
I thought it was a bad connection but I don't think so anymore. What can make the IAC motor not respond???

The guy I had fix my van had to clean the throttle body and when I got it back it did this. He had a hard time keeping it running at idle. He told me it was the throttle body needed cleaned, what gives?
Also after driving it through a misfire code in cylinder 3. I am assumin ghtis is from the IAC because everything else is new, a major tune up was done.

some hard learned info. https://dodgeforum.com/forum/2nd-gen-ram-tech/140607-why-does-the-iac-fail-so-frequently.html
understand that the IAC is an air valve that is controlled by the computer, which accepts inputs from several sources. in other words, the IAC is part of a system.
the IAC is a little stepper motor. the computer instructs it to retract when it wants the engine to run faster, and it instructs it to extend when it wants the engine to run slower. the computer tries to maintain cold idle around 1000 rpm and warm idle around 600. the computer remembers the amount of steps it usually takes to achieve these speeds, and it tells the IAC to do that. when the results are what the computer expects, then its starts hunting for the right answer.
you're not accomplishing anything good by operating it not installed on the engine. first of all, with it off, you've got a big hole in the back of the TB, so the engine will run very fast. in response, the computer will tell the IAC to extend, which it does. the computer expects the engine to slow down, but it doesn't.
what problem are you trying to fix ?
