Can you give us a bit more information on your problem, Is the car running rich, can you smell alot of gas as your driving, im assuming its a 4cyl being a GL. Is the problem there when ideling. Is it intermittent. This will all help to determine if it is ignition based or if it is computer based (electrical sensors and the like). Your engine speed sensor and your idle air control would be a great place to start, find out how much to replace you engine speed sensor and i believe that there is a sensor for the idle air control, both of these issues could cause the problems your reporting. Get back to us with more information.
