'98 Civic, LX, stock (daily driver).

Misfires cylinders #1, #4 when cold (occasional mornings, never during the day)... Goes away as soon as engine is warmed up...

I am thinking possible condensation between contact points in ignition wires-cap and to plugs? any other ideas?

 

Plug wires or distributor cap, when the insulation is starting to break down, it can do this first when it's cold & damp. Look for arcing by starting it up before dawn, with all the lights turned off.

I suppose eventually it'll get bad enough to misfire all the time.

 

With the engine running, pop the hood and mist the engine with spary bottle of water. Arcs should be visible if there's a problem. Works best with amonia water.
