4.0 idling issues
When i first start up my 94 it idles and runs fine. Once you take it down the road for a while and come to a stop the idle jumps to about 1500 with the clutch in or if you take it out of gear. If you shut it off and let it sit for a little bit it starts up and idles fine again. Ive cleaned the throttle body with a rag and some throttle body cleaner and have also replaced the throttle positioning sensor. What should i do next?
