Working on a 71 chevelle with a 454. Has a HEI dist. After reving the car up it missfires. I checked with a spark tester and when it missfires it sparts 5-6 times then no spark 1-2 times then sparks again. My thought is it has a coil going bad. The module is possable but when they have gone bad on me they loose all spark. No missfire like this is doing.

Any other ideas?

Thanks Rich

If the distributor drive gear is worn it could possibly cause the problems you are describing.Or if the bushings in the distributor housing are worn out it could cause this also.
