1 out 4 spark plugs fire.

[Hermyboy3000]

What can cause this to happen? I have a new electronic ignition module installed, new rotor, distributor cap is in good shape, brand new coil, new spark plugs, 2 year old cables. Any ideas?

Don't start another thread that is part of your previous thread, that gets way to confusing.
