Hi! I have a question about rev hang. My truck when in gear just driving around town will rev hang. Like when I pull my foot of the throttle the revs stay high until I hit the brake. If I push the clutch in the revs still stay high. Makes smooth upshifts a lil harder, but if I just take my times with shifts the revs come done normally but they will hang for a good 3-4 secs instead of coming done right as no throttle is being applied. I have checked my Throttle position sensor with a scanner and drove around with it plugged in and the TPS never hung or read anything incorrect, and checked PCV valve just to see if maybe it was stuck? Not sure it would change anything. If I am coasting in neutral the revs also hang. I am not sure what it would be. I have not really found any info on forums about it so any help would be helpful! My truck is a 97 with a 5.0l and a nv3500. Thanks!
Edit. Thought it might help to add that it has been doing it the whole time I have owned the truck. About 5Kish miles
