When I start the car for the first time for the day, it usually starts and idles at about 1000rpm for the first 10 minutes or so. Once I have driven for awhile, I idle at about 600rpm or so. There's no chugging or loss of power when driving, just when the darn thing starts.

When I "feather" the gas pedal a bit when starting it, it does fine. It chugs for a few seconds and is then fine ... strange.
