what should the timing be set at? I know to unplug the wire under the carpet on the passenger side, and also MT- since it like like the IAC is not moving freely, can I take it out, leave it plugged in, turn the key to on and push the throttle to see how its moving? Or does it have to be running? I seen a thread of how to take one apart and clean it, I tried that on an old one but it wouldnt come apart.
