codes. I have changed the coils and plugs and the codes are still there. What are chances that it could be the catalytic converter being plugged or bad fuel filter? I would think that if the problem lies within that all codes for cylinder would be on. Just seams to be that 2 ,4 and 6 cylinders affected. Please Help!
