after seeing everyone have positive input for everyones problems I decided to register for your help. go me. i have a 98 countour se sport 90k miles 2.5 v6 and after driving on the freeway, everytime i accelerate (after stop signs lights) my car jerks when shifting gears. sometimes it is severe, it jerks and it even makes the tires squeal on the road...I'm thinking that its probably my trans going. Any ideas??? CEL also keeps coming on and off i dont know if that has anything to do with it. Another problem my gas mileage is terrible. I checked all the basic stuff( tire PSI, filters all ok) when i start it up strong gasoline smell coming form exhaust. please help me! I'm on my last nerve with this car!!!! :shocked:
