My throttle was sticking closed after sitting at idle, like while I was waiting for a light to change. I examined the operation of the throttle valve, which seems to be a butterfly valve plate that rotates inside of a circular tube, similar to the classic carb. Evidently, the problem was that the plate was closing too far and binding against the inner wall. This could be demonstrated without the engine runnning by pushing on the throttle to close it tightly, which would cause it to stick. Pushing it closed lightly caused it to stick slightly, so there was a correlation indicating this as the problem. The solution is simple. Just adjust the limit screw that keeps the plate from fully returning and getting stuck. You will find the screw right on top of the throttle assembly, with a small nut to lock it in place.
All of the discussion about cleaning the throttle body seems pointless and over-complicated, if my solution works.

Steve, I'm trying to replace my 2000 Quest driver power window switch. I clicked on your picture file name in the post #1825, but there is no picture posted. Your pictures will be very helpful.

I put one pic up in one of my CarSpace albums. Here's the direct link. If you need something different let me know and I'll borrow the camera again.
Mine is starting to act up again. I'm going to try the electrical contact cleaner spray soon and try to avoid cutting into it again.

I got only one picture, but it seems like you posted more detailed pictures in the post # 1825 (?). I think that'll be more helpful than the one you posted. Those pictures in the post # 1825 can't be downloaded any more.

I just checked my photos on my computer and that's the same one that's in the album; the rest of mine are similar - just show the cutting into the plastic to expose the switch. Here's one of the side of the switch:

Getting the switch out of the door is easy; one screw hidden under a little plastic cap in the handle as I recall removes the whole handle section(don't have the van handy today). Then you can unscrew the switch from the handle section and unhook the wiring harnesses.
Someone posted about flooding the switch with the contact cleaner so I would try that before taking a hacksaw to the switch. I don't see that post but here's one where an owner was able to get to the innards without destroying the top like I did:
