2000 Villager - when starting cold, it idles fast (about 1500 rpm) until it warms up a bit then goes back down to normal.

Fuel Injected so no choke right? Any idea? Thanks!

Have you tryed cleaning MAF sensor with MAF sensor cleaner and clean throttle body.

I think you have nothing to worry about. Our '99 does that too. I'd be worried if it was revving at 2k rpms or more.

Mine does that (I live in Canada, so its COLD in winter). Its supposed to do that.
