    2000 deville keeps accelorating

    When i start the car its idled high and when i put it in gear it jerks and i dont have to hit the gas to pull off. It steadily speeds up got up to 45 without hitting gas would go higher but i hit the brakes. Any idea guys thanks.

    ----------------------------------
    check/clean the throttle body - like Ranger suggested -

    also check for Diagnostic Trouble Codes -

    if you don't know how - go here and read the ENTIRE post -

    http://www.cadillacforums.com/forums...odes-dtcs.html

    if you have any codes - post them here -
    ALONG WITH THEIR DEFINITIONS
