I got a problem with my idle.... Whenever i turn on my vents, my vacumm gauge goes from about 18 to 16 and then i start to idle all crazy... crazy as in it goes from about 600rpm to 2,000rpm ranging. Almost dies. Anyone know what this could be from? I did take out my STOCK intake to put in a new radiator. But I slipped it right back into place, hard to put it in wrong but maybe I did? Anyone know? Thanks alot.
