    RPM at Start

    My 02 3.3 revs rather high upon initial startup.Around 2000 rpm.It drops right down,but I am curious if this is normal.

    Totally normal. It has happened on virtually every fuel injected car I've ever owned (18 in total between my wife and myself).

    I think the noise coming from the accessory drive makes this one sound worse than it otherwise might.

    Yeah, when you start it up, it'll quickly "flash" to 1500-2000 RPM or so, then quickly drop down to 1100-1200. Hot idle should be about 600-700 RPM or so.

    What he said.. Although when the temps drop down below 10-15 *F here, the engine holds 1800-2000 rpms for maybe 3-5 seconds on a cold start.

    sounds about right to me (drove my dads van once and nearly freaked out when i couldn't hear the engine running then looked at the tach and it read about 600 rpm). But its totally normal for the car to jump up around 2000rpm at first, then drop down around 800-900 rpm for the cold idle. Every non-carbureted car I've ever driven has always done this.
    Im 24 and my parents own a 2007 Dodge Caliber SXT (1.8l 74k miles 5spd), a 2005 Dodge Grand Caravan SXT(3.8l 41TE 106k miles), a 2001 Chrysler PT Cruiser ((which is mine) 2.4l 115k miles 41TE), 2000 Ford Mustang base (3.8l, 4 spd auto 26k miles), and a 2000 Dodge Grand Caravan Sport(sold @ 122337 miles)

    Colder temps can make it flare higher than normal.
    I know lots of the diesel guys are freaked out because their trucks are idling at 1000-1200 rpm when cold when their used to 800 rpm idle speed.
    It's just due to the colder than normal winter some places are getting.
    Their trucks always had that feature they just never got that cold before.
