When i rev the truck up to about 1500 or 2000 RPM and let off it drops to about 500 then goes to 750.... Sounds like it almost cuts out when it drops.

 

Pull the throttle body, remove the IAC valve from the back of it, and clean all the passages really good. Reinstall with a new TB gasket. (they are like two bucks at the parts store....) Have the battery disconnected while you play. Once its all back together, start it up, and see if it doesn't feel better.

 

About how long should it take to get the IAC off and what do i have to take off to get it? Sorry, not a mechanic..... YET! ha

 

The hole job shouldn't take much more than 30 minutes or so. I think all you need is a 10mm socket for the TB bolts, and something similar for the IAC motor. It's only two little bolts that hold it on.

Anywhere from one, to three cables, depending on your truck, and three electrical connections, and that's it.

 

I cleaned it up today and it fixed the problem. Thanx ALOT. i have a ? that may be related to it also though. When i give it gas the RPM goes up i let off the gas. Then the RPM stays up steady for about 2-3 seconds then goes back to 750 slowly. Is this a problem? If it is what could be a possible fix?

 

The PCM probably holds the rpm for a bit, just in case you are 'shifting gears', or some such nonsense..... If it isn't really a problem for you, then, it isn't a problem.
