1995 Cavalier rough running condition

My 1995 Cavalier will idle quite well, but when I accelerate, I get a rough running condition. If standing still at a light or parking and turn on the AC, the car runs extremely rough as well. This condition happens whether hot or cold. The check engine light has not come on at all.

Thanks for your help

is it a 2.2 or a 2.3?

Sorry about that, 2.2
