Amy Posted May 20, 2007 Report Share Posted May 20, 2007 The car runs fine until I turn on the heater or AC.. If the cars RPM's are up it runs but if I let it go into idle it just dies, everytime. ????????????? Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted May 20, 2007 Report Share Posted May 20, 2007 sounds like it is not kicking the idle up during a/c operation. that would be in the tune. Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted May 20, 2007 Report Share Posted May 20, 2007 what kind of car? the computer should use the iac to raise idle speed when the ac is engaged you could have a sticking iac a fualty ac pressure switch ( tells the comp the ac is on) bad computer , also rarely a marginal battery/alternator will cuase this problem not enough power to run all the extra stuff Quote Link to comment Share on other sites More sharing options...
