Rough idle

I have a 1995 Buick LeSabre. The car has a rough idle when in gear such as drive or reverse, but not when it is in park. I have already changed the plugs and wires. The alternator and battery have been checked and are working fine. What could be the problem?

Since you've changed the plugs and wires, my next guess would be either a vacuum leak or a clogged fuel filter.

Hello

Any check engine light? Have you checked for codes which could be present even without a CEL.
