Try some ice cold medium or retracted gap plugs gapped to .015" to .0= 10". This will show up a secondary ignition problem. If the problem goes= away, the voltage at the plug is too low for conditions. Mazda plugs are= too high a heat range

Be sure primary ignition wires are run well away from secondary ignit= ion wires, and away from each other.
