What's happening

Currently I'm in the process of tuning up the ignition system by replacing the distributor caps and rotors, plugs and plugwires.

The reason for this is that I discovered the drivers side coil-distributor cable had a nasty cut in it due to the cable strip BMW has used to hold it in place with a hose. This caused sparking to nearby ground and almost made the plastic in that area melt away.
