    High idle..

    So, I bought a used (subaru certified) '06 WRX in the recent past with 15k miles on it. Everytime I turn on the engine (unless the engine is already hot from only have been off a few mins) it idles at around 1,500 rpms. I cant remember this happening with other cars ive had. It will idle there for a few mins and slooowly come down. But I usually dont wait long enough for it to come down before i start driving, unless its cold outside. Once i start driving after a few mins, it starts to normally idle around 600 or so. I havent experienced any problems yet, i just didnt know if this was very abnormal or not? Any thoughts or explanations would be helpful.

    Perfectly normal. The computer raises the idle rpm when the engine is cold to try to warm it up more quickly. Nothing to worry about. It helps get the fluids warm and flowing, warms up the cat to help with emissions, warms up the combustion chambers to reduce emissions, etc.

    Back in the days of carburetors, you would have to sit there with it "racing" for a few minutes, then tap the accelerator to "kick it down." I had an old Monte Carlo that did it. It was annoying.
