1989 Pontiac Grand Prix 4 cyl Two Wheel Drive Automatic

What would make a pontiac grand prix 89 not start sometimes, Stall, hesitate to go when pushed on gas, then catches up. Idles when car is first started. Engine light sometimes comes on. We have replaced the spark plugs, EGR the fuel injectors, air filter. & Have had fuel cleaner.
