FAILURE TO ACCELERATE, ESPECIALLY WITH AC

2004 Saturn L300

Engine Performance problem
2004 Saturn L300 4 cyl Two Wheel Drive Automatic 36252 miles

My car has substantial engine acceleration issues. When trying to speed up the engine revs but pickup is very slow. The problem is worse when the AC is on. The regular fuel injector cleaner and better gas tries have failed. The onboard computer was checked at an auto parts store but showed all was fine. Also, the battary and alternator have been checked and they are fine also.
