If it's weak you might have incomplete combustion or possibly an irratic misfire, but most likely the problem that causes increased emissions is elsewhere. An increase in hydrocarbons is often caused by the O2 sensor or possibly the EGR valve. You could also have a problem with plugs, distributor, rotor or plug wires.

On a high energy ignition, possible problems include: Faulty keyswitch, faulty wiring or connectors, faulty pickup inside the distributor, faulty electrical condenser, if it has points (depends on the type of HEI) the points could be bad, faulty coil or faulty HEI control module.
