    when my saturn sits or idles it omits black sooty residue out the exhaust,
    also the check engine light comes intermittly. I have changed the head
    gasket, plugs, oxygen sensor, pcv valve. It clears up when you drive the
    car, but once you idle, or shut the car off and dont start for sometime it
    starts all over again. the exhaust fumes smell fuel rich. Does anyone have
    any ideas?

    Check the CTS (coolant temperature sensor) may be telling puter the engine
    is cold and needs more fuel.

    I'd check for that or the possibility of a stuck open injector. Does it idle
    high?
