Check your vacum lines, and check the little pump thing that holds your throttle open sometimes. You'll see it by the throttle cable. In a lot of cases, it's a worn out, or plugged vacum line. Those are a pain to find. You just start the motor and start pulling lines off and replacing them until the rpm doesn't change or goes down.

i had a look at all the vac hoses and they are all ok i cant find any leaks on them what so evey. i did a test on the IAC valve with a ohmmeter and it was a bit to high so i got a new one tested that befor putting it on and the reading where perfect. put it on but still no different still sitting at 2000 rpm im thinking off changing all of the IAC valve because i only change the the magnet thing. how do you just change the idel speed or cant you.
