94 civic RPM help!
I have 94 civic coupe with a d16z6, it's automatic, when Im driving and I am coming to a stop.. as my RPMs are coming down to about 900, they will start jumping up and down from like 900 to 1500 constantly, and I am able to hear the engine revving itself... and it will do this until I come to a complete stop... what could be the problem? I changed out my IACV already.. but its stilll doing it... please help if you can thanks

Vacuum leak, low on coolant, Fit valve out of adjustment, have you checked these things? Was the IACV you replaced it with new, used?

well i haven't messed around with the FITV.. would cleaning it help?
and the IACV wasn't new but i got it off of a friend and it worked fine...
also what's the best way to check for vacuum leaks?

You can spray carb cleaner around your intake and vacuum lines, and if you do have one you will notice a change in the engine pitch, can't remember if it idles up or down. Sometimes you can here a vacuum leak. I cleaned my fitv before when my car did that and it helped it, they tend to unscrew themselves.
