    Did you check the codes to see if it was something serious?

    Go by Auto Zone and they'll read it for free, since it's been on a while might have a couple things going on. I'd recommend getting it read and posting the code(s), but if you want to try and reset it you can - some codes throw a light immediately, some take a few ignition cycles:

    PCM Reset
    Turn key on, don't start car
    Pull PCM BATT and PCM IGN fuses in engine compartment
    Wait 5-10 min
    Turn ignition off
    Replace fuses
    Idle will need a few minutes to relearn, and will reset all the readiness tests, so if you're trying to reset it to get through OBDII emissions testing you'll need to put some miles/cycles on it before getting tested - after fixing the problem.
