I have a 1994 grand am with a quad motor. It is running ruff. Feels like it is running off 3 cyl. Changed out spark plugs. And still have the problem.

Start with the oxygen sensor and idle air control valve and then throttle positon sensor-I'm not aware of any common problems with this vehicle-there's numerous things that can cause your problem-could be compression/fuel and spark everything has to come together for it to run smooth-its hard to say where its coming from-extensive diagnostics has to be performed.

Mileage at 220K's miles there's wear and tear
