okay i have a 91 ls 5spd and recently my distributor went so i replaced it and i noticed that every time when i go to take off from 1st the car kind of bogs down almost like it is going to stall out and then it revives itself and has full power. i thought maybe it was the plugs or the wires because the wires are old but i put new plugs in about 2 months ago and i have recently changed the oil and filter also changed the fuel filter.
