my car runs rough. And white smoke is coming out of the tail pipe. It runs rough when climbing a hill. I had the cat replaced. the check engine light is not on. i did a tune up but no change, i also replace the fuel filter some change but then it runs rough again. it seems to be using a lot of fuel.
