I think we have a winner!
Replace all your spark plug wires and the wire to the coil and repair that burned wire (figure out why it burned) and you'll probably be amazed at the difference.
Pull the wires off one at a time and follow the same threading around the engine.
Match the one you pulled off with the closest size ones from the pack.
Good sparky wires have differing lengths for each cyl, the generic ones from Autozone will only have 2 sizes of wires. (the local AZ always has a set in stock and they have a lifetime warranty...)
They are OK to use, I have had a set of them for a few years, but there will be some extra wire to deal with.

We will all be interested in looking at this engine on Friday.
