replaced opti but car runs rough time to time i recently had my opti replaced along with new plugs and wires. From time to time when i come to a stop it starts idling rough, and when im accelerating or just driving it bogs and seems to be lacking power. also some black smoke when coming down after reving it up. Other times it runs awesome i can feel all the power through out the rpms. i need to replace an o2 sensor would this make it run rough? Could this be my fuel filter? Anything else that could make this happen?
