    either throttle position sensor of clogged injector in the throttle body. have you ever run injector cleaner. this should be done about every 5-6 tanks of fuel.

    IF 'stock' Tuned Port Injection (TPI) system, clean throttle body and check for a vacuum leak. Possible idle air control sticking. Injector cleaner with Chevron Techron recommended, if you are going to add any, might as well be something that works, this does!
