'07 Aveo Sedan idle's high on startup

Yeah, its way off topic, but the original question was answered.

Every time I start my car, it idles unusually high at about 1500 RPMS for maybe 15 seconds. Then, it goes back down to normal idle, ~900-1000. It's enough to be annoying, but it goes away without any user input. Ideas?

My 2006 does this also for about 5 to 10 seconds.
I thought it had to do with the choke disengaging, but who knows.
Looks like they all do it.

yes... pretty much every car that is fuel injected will do this.

1500rpm is rather a bit high... mine does the same thing but only within 900-1000 same within 5-10sec, have you tried to scan the ECU?

Its perfectly normal to idle high on startup. Its the computer's way of warming the engine up for emissions and proper operating temperature.

With my recent experience with moving gauges back and forth (I also have a spare cluster I bought from eBay a while back for spare parts) i learned that what they say is true: the gauges are only there for reference, not exact measurements.

That's a good point though..
