I have an 88 jeep cherokee that has a mind of it's own.It's idle when started pegs at three grand.If i unplug the tps,or vacum to the map idle drops to normal.when i plug the map vacum back up it pegs at three grand.If i plug the tps back up it idles at 1500 rpm.I replaced the tps about a month ago and thought it was fixed.It's back now.Have already tried ect,map.no change.ANY IDEAS?
