engine runs hard while warming

  1. heres my problem... I start my 98 SL1, it runs really hard. like its
    missing; and there is kinda sputtering from the exhaust. I have tried to
    isolate cylinders by pulling spark plug wires. no help they all seem to be
    running. I drive my car and as I accelerate through the gears it continues
    to miss. After a few miles I pull over and check it out under the hood.
    And I check the vaccum hoses and all is brand new anyway. By the time I
    get back in my car, engine runs great. No further problems. Until the
    engine has had a long time to cool down. Seems kinda crazy, because when
    It warms up, it really runs good. Would appreciate some help..
