if you know engine fairly well the sensor should be pretty easy to spot it will be coming out of the cylinder head and have a wire attached to it although I haven't done much work on those models I wasn't aware they had that type of sensor are you sure your not looking for the temp sending unit? if so you will need to look on the intake manifold or near the water pump either way you may consider buying the sensor first then matching it with the wire/wires coming into it then simply unplug that sensor and unscrew (standard threads) make sure to properly seal the threads on the new one tighten to spec (be careful not to over tighten this component more than likely will thread into aluminum threads) better to be to loose and have to be tightened again than to have to replace a major component

I CAN TOTALLY FIX THIS!!!! I just fixed this problem with mine! I have been fighting with it for 2 yrs. You need to replace you PCV valve if it is bad. And then clean out your IAC (ignition air control) take it off completely and spray the whole inside with with carb cleaner or brake cleaner scrape all the carbon build up out of it and work the spring in there untill it opens and closes easily! you gotta really work it though, once you have it all cleaned out put it all back together and it should work! When i did it it instantly fixed my truck!
