My car, Ford Contour svt, 2.5, v6. 1998. Choppy very much. I have changed gas filter, oxygen sensors, plug wires,cleaned manifold etc. Nobodys knows what is wrong about this car. Even all kind of services firms. No matter what is rpm, still choppy. Sorry my english, I`m from finland :)

Your English is fine. Since you have checked / replaced so much, I feel that either you have an injector that is bad, low compression on one cylinder or you have a plug wire that is switch. Check that and let me know what you find. Also, make sure the fuel pump pressure is within the manufacturer's specs. check mass airflow sensor.
