i got b16 into a 91 si and i start her up and she runs good, if i stop at the store and turn her off and start up back up and drive away the car starts to jerk hard, example: the car is in 2nd and i press the gas and release car jerks, press the gas and it starts goin bad n forth any ideas??

 

could be a dirty fuel filter

 

i changed it

 

I'd stay keep working with the fuel system. Fuel pump maybe?

 

i was told it could be bad dizzy, any more on this?
