I own a 1992 Civic Si hatchback 5-speed.it has 174800 miles on it. The car has a new timing belt and water pump, as well as a new fuel filter. I was driving the car tonight and it started to buck at about 2,000 rpm, any ideas out there please help me.

 

ignition coil did that to me one time. for a long time. couldn't figure it out.
