98 2.5 5 speed ghost idle rising??
98 2.5 with 5 speed trans. every now and then (not all the time) my truck will raise the idle by itself without me touching the throttle, only after i am cruising and take it out of 5th gear or so to slow down or stop and throw it in neutral; the rpm's will stay at the cruising rpm (2000 or so) and then start to ride, i've seen 2500 or 3000. then when i stop it all the sudden drops to normal idle rpm. just started doin this yesterday so im not familiar with all the issues yet, just a little ackward. it's acting as though your starting the truck up and getting the initial high idle, except it isn't dropping back down, and sometimes it's going higher.
where do i start with this ghost idle?
