Hey, I am pulling this code on a 1996 mazda millenia with 2.5 engine, 131k miles. I have changed all spark plugs and rotor cap. I have also replaced the cylinder 3 fuel injector. My spark plug wires are only 30 k miles old so I didn't replace them, maybe I should have. Car accelerates terribly and doesn't idle well either. Car actually runs pretty good until warm. Any ideas?
