rough idling on 1993 Chevrolet Cavalier

About 2 months ago my car started to idle very badly. I took it somewhere and they said it was my spark plugs so I had them change it hoping it would fix it well it didn't. Took it somewhere else and they told me they couldn't figure it out. I need help because it getting worse.

you will need it scanned if the engine light is on. if not, rough idle on those engines are usually caused by old plug wires. even if they look good to the eye, they short out inside the insulator. new wires makes a world of difference.

I had the spark plugs and wires changed. They even changed the fuel pump. They just don't know what else it could be.
