Still having misfire issues with the E28. Here is the latest video.

Seeming to be a spark issue, I started in to take a look at the distributor cap and rotor. Of course to get there you need to remove the fan and shroud.

Other than that it was pretty easy to remove. This is my first car with a distributor, so I don’t know how worn is too worn, but it didn’t look good.

I cleaned the rotor and points off with a wire brush. Not sure you are even supposed to do that?

Anyway, I went inside and ordered a new cap, rotor, and spark plug wires from FCPEuro.

[Though on a side note as good as FCPEuro is, every time I put in my BMW as a 1988 535i it forces it to be an E34, not E28. I have to put it in as a 1987, not sure why.]

With parts ordered and on the way (thought probably not until after the holiday weekend), I decided to go ahead and reassemble everything to see if it ran any differently.

Did it?

Yes, yes it did. MUCH worse. I barely made it around the block, with the engine completely dying twice. Maybe a bit too aggressive with the wire brush?

So no cruising in the E28 this weekend. I’ll just pull the fan and shroud so I have easy access when the parts arrive, and maybe tackle the trunk gasket / seal finally.
