If your in a hurrey to find the problem a scanner will help. If you want to do it yourself and take a chance just try doing three things. Replace the air filter, and put new plugs in it, use NGK or Champions.
The throttle plate may also be dirty along with the throttle body, idle speed motor(called a idle air control motor) bore and the motor can be cleaned. If that does not work, well you have tried and you have eliminated the most likely cause, remember you have high mileage so there could be other problems. Ok
