I've never had any luck with anything that has Accell stamped on it. If you have a decent multimeter Check the resistance of each plug wire. Anything over 500 ohms, IMHO, is too much. How old is the module in the distributor? What kind of cap and rotor bug? The module is solid state and normally they either work or don't. The cap and rotor if they are cheap can ark between contacts. I like something with a high dielectric strength.
