You could just have dirt / oil / road magnetic particles on your ignition
wires, coil top, distributor cap or holding moisture in the spark plug
seals.
Give the engine a good spray down with Gunk Engine Cleaner, wipe out the
inside of the distributor cap and just generally give the engine a good
brushing with the cleaner before you hose it off. Pay particular attention
to removing the coil and distributor wire and check down in the wire ports
for corrosion.
