Hmm....my 4.7 H.O in my WJ drops to super low idle mode when coming to a stop sometimes....it drops and idles at 400 rpm's...but has never stalled...

I cleaned out the IAC chamber and motor, and still nothing..same thing...I dunno if its a glitch somewhere in the computer system, or if its the IAC motor thats actually bad...

Yeah...I dunno...I was thinking perhaps when I do the superchips flash that it might perk up/smooth out the idle..

1500 rpm idle....something is wayyyyyyyyy wrong!! I'd say the throttle position sensor perhaps your case Paul. That sensor isn't sending the computer the right info...that would be my first guess..
