1994 Isuzu Rodeo 3.2 Liter SOHC High Idle Problem!

So maybe somebody out there can help me shed some light on an issue I am having with my '94 isuzu rodeo? The problem I'm experiencing is a very high idle about 30 seconds after starting my engine. I'm talking about 3,000 to 3,500 rpms high! I replaced my throttle position sensor thinking this might be the culprit. Nothing. Still idles high. Next I thought it may be the pcv valve. Replaced that. Still nothing. Next I went and purchased some brake cleaner. Sprayed it while my engine was running around my vacuum lines hoping to find a leak. Again nothing. I'm stumped, and not very familiar with a 3.2 liter SOHC engine. Anybody every run into this problem before? Any suggestions would be appreciated! Thanks!

It could be a defective Idle Control Valve or Coolant Temp Sensor.
