high idle

Just bought on 09 2.4 automatic fwd Vibe, and noticed that the idle after a cold start stays around 1500 for about a minute before dropping to 1000 rpm or so. Does anyone else experience this situation, do you just put it in drive and go anyway, or do you sit and idle for a minute before driving off?

I noticed this on mine too. I'm not sure I agree all cars do it-at least to this level. I had a GM 3100 for 7 years/125K and a 3800 for 2 years 25K and they didn't jump up like quite this high. It also seems like it will do it after 10 minutes as opposed to overnight. I just have gotten a little more used to it.

cars used to do this many years ago, but most modern cars seem to have a stable idle even after a cold start closer to 1000 rpm, not 1500. Just wondering if this was common, in which case I wonder how the 5 speed auto tranny will hold up long term. At least we are coverd for 5 years.

its called open loop. basicly it allows the car to build up to operating temperature by having the car run a little more rich until you reach optimal temperatures. 99.9% of all OBD II cars do this.
