rough running on 1995 Oldsmobile Cutlass Supreme

Car just started running rough, run good for about 15 miles stopped at a light started idling rough then on take off it really run rough.

It sounds like your 1995 Oldsmobile Cutlass Supreme may have developed an engine misfire. Checking the ignition coil towers for corrosion and the spark plug wires for being open would be the first steps.
Would it start running rough just like that, because I was driving then stop at a light then it started running rough
