enferno Member Jun 20, 2006 418 2 16 Aug 29, 2007 #1 Aug 29, 2007 #1 my buddy has a 01 mustang with a v6 in it and MT. his idle wants to drop when the a/c is turned on. i don't know much about late models, but is there an a/c idle compensation circuit or something? or would something else cause this? how to fix it?
