I recently replaced my spark plugs, which could've been original. I noticed improvements immediately following completion. All gapped to .35. Cranked and ran better didn't have to prime it as much or as often, but 1 day later issues returned. It has been getting colder.
Had an incident where she would not crank at all, to the point that I was losing power (lights flickering etc. before she finally cranked up, never actually died though.

Take the alt. off and have it tested at most autoparts stores for free.

I would have changed the wires and coil while I was at it.
