    I have a 1995 DOHC SW2. Once in awhile, when stopped and in neutral, my RPMs will rise from 800 to 1700, then, but not always slowly drop back to 800. If I turn then engine off, in the stopped position, then start again, it will go back to 800. Any suggestions ? thank you from DOVETAIL.

    Clean your throttle body.

    Otherwise I suspect throttle position sensor TPS.
    There is no relearn procedure for throttle body position, so that's that
