you are kidding, right?Better shot of center wore on distributor cap.
that cap has totally had it, finito, period, chuck it in the trash.
the leads will be shot too, throw them out
and I bet the Rotor has had it too.
and the coil, where the king lead fits into is probably not good either
These connections need to be brand spanking shiny new.....anything less is asking for trouble........no wonder you have a slow to start......it's amazing it starts at all
When you replace all those, let us know
Get a Bosch cap and a Bosch rotor, not some aftermarket cheapo thing.
(btw: no, you do not need to disconnect the battery to undo that stuff)
we are making progress
