2001 Kia Sephia. Thought I got water in my gas, used gas line antifreeze, along with a fresh tank of gas, no better. Goes great as long as giving it the gas, when I let off, hesitates quite badly, and sounds as if it needs to backfire. I smelled gas when I started it today, not bad, but faintly. Now, the gas smell is getting worse. The exhaust coming out is not study, more sputtering, and again the smell of gas. No rotten egg smell, or sulphur smell, but not convinced it's not the catalytic converter. When I'm driving, once in a while, I hear a little knock near the area under where my feet are. Desperate, please help!!!!
