Sounds like one cylinder is not firing properly.  Try removing one of the
spark plug wires at the distributer end & see it the problem is worse.  If so,
reconnect and keep trying all the plugs.  If it does NOT get worse when the
plug wire is disconnected, you've found the problem cylinder.  Could be a bad
spark plug, perhaps a bad injector.

Good luck,
