When checking the IAC and having a friend turn the ignition on how much should the IAC move in and out? With mine, the valve will move in a little, then vibrate for a second like it wants to go in more, and then move back out to the original location. Is that normal? Or should it move in and back out smoothly?

Also when adjusting these items, is there a correct order in which to adjust them? The TPS, BISSS, and the Idle/Throttle switch?

Probably easy questions, but something im not fimiliar with. Thanks!

This is what the ISC is supposed to sound and act like when power is applied.

DSM ISC - YouTube

Exactly what i was looking for man thank you! I searched youtube but was putting in IAC, never tried ISC. Thanks again.

If there is any correct order in adjusting those few things someone let me know. I wouldnt think it would matter too much. I just think the last thing to do would always be the Throttle/idle switch. Thanks in advance!
