Occasionally my 88 MJ will have a high idle almost like it has a vaccum leak somewhere. Sometimes a quick tap on the throttle makes it go away and other times it doesn't. The truck started doing this after installing a bored out TB. I put the old one back on and the problem went away but has recently returned making me believe it has nothing to do with the TB. I sprayed around both TB's with WD-40 looking for the leak but nothing seemed to work. Could it be a sticky IAC motor?
