i have a 91 intgra GS and it was running kind of shitty so i changed the fuel filter and did an oil change to it. after all that was done i went to take it for a ride and the car did nothing but stutter and jerk every time that i shifted. so i continued to drive it thinking maybe it just need to run some fuel through the filter and that did nothing so now my car barely starts any more and i have no idea on what to do.
