IAC problem

I recently purchased my 3rd Ranger, a 1998 2wd with a 2.5, 5spd. When I bought it, it would not run on high idle when cold, but would run great after it warmed up. I talked to a mechanic friend of mine and he told me to clean the idle air control valve and the problem may go away. I cleaned it and it ran at 2000 to 2500 rpm all the time, so I bought a new one and installed it and still have the same problem, any ideas?
