Hey guys I have a 2002 Camaro SS. My car started running really bad about a month ago. It would run fine for a while and then would sputter and wouldnt accelerate until full throttle. At around 70mph it would run fine but slower speeds it would do this. Now the car runs about 1 mile just fine and then starts sputtering and shaking but will still go just wont accelerate. Sounds like a 4 cylinder car on alcohol. There is a really strong smell of gas as well. Any help would be apreciated. I have changed the fuel filter..........
