I am driving a 2002 Altima and all of a sudden the car start to jerk hard, I was pushing on the gas and nothing would happen. This would happen serval times. I got the air filter clean it ran better. Then I was told I need it to change the transmission fluid. I did that but it is worse. I have been told that the car shouldn't perform like this because of a transmission. Not the person is telling me I need a new transmission Help!!!
Check the fuel pressure,may just be bad fuel pump,doing this,before you shell out money on tranny.
If it runs worse as it warms up, you may want to look at catalytic converters...they are easy to diagnose...just loosen the exhaust in front of the cat..it will be loud, but if your engine runs better and revs up, it's the cats...
