That could be a weak spark coil, tracking in the distributor cap, voltage
leak from the spark plug wires or the wrong spark plug wires or even the
wrong spark plugs.
Other than that it could be low fuel pressure.
The above statements could be true but timing is a consideration so be sure
your distributor advance is working properly.
