After doing a tune up and replacing wire and spark plugs and cleaning the egr valve it still runs rough and has no power. I checked it at autozone and its reading a multiple misfire and egr valve. After looking at the exhaust i noticed the car is rich out the tail pipe. Can really smell gas from it. Could the egr valve really cause that? Or is there an underlined problem?
