Its more likely to act like that if the timing is to slow. If you are timed right & sure the wires are correct its time to pull the valve covers & make sure they are all opening & closing about the same amount. If one is not it would indicate a bad camshaft. Check for a valve sticking up higher then the rest. That could indicate a recessed seat.
