Guest Sue Bell Posted June 14, 2008 Share Posted June 14, 2008 IF I ADJUST THE IDLE ON MY 1989 CHRYSLER TC WILL THE COMPUTER RESET IT TO WHERE IT WAS? IT'S A 4CYL. AUTO. Link to comment Share on other sites More sharing options...
TwinCamFan Posted June 14, 2008 Share Posted June 14, 2008 The idle is computer control by the AIS or Automatic Idle Speed motor, it is a little stepper motor on the side of the throttle body that opens and closes to bypass air (thereby increasing the idle speed) around the throttle plate. I think the real issue is why are you adjusting the idle? Is it too high? Too low? Engine stalling? You are going to have to be more descriptive with the problem, remember, we're not there seeing it ALan Link to comment Share on other sites More sharing options...
