Your car has on board diagnostics level one (OBD1) it monitors 21 possible different faults but only looks at open or shorts not performance. Does the car accelerate well and sustain throttle? If not you could have a failing fuel pump or low fuel pressure/delivery, perhaps change the fuel filter if it has not been changed recently. Many people over look valve adjustment on your model car, that engine has "screw adjust" valve, it definitely affects engine performance. Check your spark plugs and clean the throttle butterfly housing. After that you have cover a basic tune up. Its hard to guess at what is wrong without being able to drive your car and experience the problem and do some basic diagnostic tests.
