Sits right on top, silver, held in by 2 bolts. Easiest do it yourself there is on the MPV.

I just bought one tonight [been following this on another blog] tho years ago I readjusted the throttle stop to largely obviate the problem. AutoZone had it for $46.99 + tax. The sleepy-sounding guy at Oreilly said they don't carry the part. Buy it & look at it's appearance & you'll see the original near the top of the engine, held on by 2 small bolts & plugged into a fairly simple electrical connector. Remember it's bolted into aluminum so be careful unbolting & rebolting. make sure you use a good quality METRIC socket the correct size; not an almost-right SAE size, NOR an open-end wrench & DON'T over-tighten.. Should be pretty easy. Good Luck, BK
#74 of 76 Engine Revs up at Start-up

One in about every 5 times when I start the engine on my 2003 MPV the engine revs up real high. I am not pushing down on the accelator pedal at all. I also never push on it prior to starting the engine. I am thinking it might be the position switch but dont know why this happens intermittenly. Any help would be greatly appreciated.

Just a guess, but your idle air control valve could be sticking. They can get carbon build up on the inside. Easy repair, sits right on top with 2 screws holding it in. You could either clean it or replace it ($60)
If you've never replaced, may be worth giving it a try. It has been a bit of sore spot with MPV owners. I replaced mine a couple years ago.
