It really is not hard to clean or replace. I just did mine and bought it thru the dealer and got the entire body with sensors and all for $330 I replaced it and had to get my PCM updated. I think that my problem was the PCM being outdated and not the TB. Took about 20 minutes to change.

A new throttle body is expensive. Autozone wants $599 for a TB for my 06. Therefore, I'd remove that thing and clean it thoroughly on the bench. According to my Haynes manual, there's only three steps to removing the throttle body so it's quick and easy. I understand there's some plastic parts, so be careful not to "heavy hand" them or over tourque the mounting nuts during re-installation. On carburetors, only 10 foot pounds of torque is needed to tighten the thing down (in correct sequence too) and there's not a lot of difference in the mounting of a throttle body and a carb, so be gentle.
If memory serves me correctly, the throttle body has a special coating on the inside that must not be damaged during cleaning, so be careful what you clean it with. However, my memory is not perfect, and my Haynes manual does not mention it, so you need to double check this information for yourself. (Perhaps someone on this board will confirm this). At the very least, I would ask my auto parts guy what to clean it with and google it too. But if one of those young kids or girls is behind the auto parts counter, don't waste your time because they do not know anything about cars or trucks. When I need good information, I go to the local NAPA parts store. At my local store, they just happen to employ some "old heads" who know all that stuff and will readily share, especially if you buy the parts from them. However, NAPA is not the only parts store that employs knowledgeable people, so you may have to look around or ask. It's actually worth paying a little more just to get access to the experienced people.
Good luck and let us know how things turn out.

I just too mine off to clean and when I first looked at it, the outside was clean. As soon as it was off the truck it was another story. I was getting the trouble code for low rpms, so I desided to clean it. WOW was that thing nasty. If you are running an CAI with an KandN then I would clean the MAF and that. The oil from the KandN will gunk up your TB... just my two cents.
MAF and TB cleaner was under 15 bucks... not sure on what a new TB cost, but its got to be cheaper.

thats what I meant to say. the picture above is with it completely unplugged and not forcing the door open at all. I cleaned everything as best as I could but it still wouldn't shut all the way. Is it time for a new one?
