I was told that the EGR valve needs replaced along with spark plugs, wires, and distributer. Its a 97 model with electric EGR valve. The symptom is my car does not accelerate. I can shift gear. I can rev the engine in park. When I drive around I can pres on the gass and nothing happens. The car will move but very slowly.
