I have a 2000 4.0 cherokee classic and the engine just started to idle slow I think its the IAC but I dont know which vlv it is on the throttle body ...can some one send me a pic to describe the diff vlvs on the tb,,I an new here so I hope Im in the rite place....tks Terry

 

I honestly dont remember but you could go to Autozone.com and look up the IAC for our cherokee and see what it looks like... then match it with the one on your throttle body... im thinking its he one coming in from the front... but double check... most people should know this on here but may be just as fast to check yourself like above! Welcome and goodluck! Youll find theres alot of help here on this site... unlike alot of others... i think anyways...
