Replacing rotor
I've been having a slight miss with my 91 L98. I checked the fuel pressure and it is good, I've replaced the damaged spark plug wires and the spark plugs which were the wrong ones installed by a mechanic. I pulled the cap on the distributor and took pictures of the cap and the rotor. The cap looked fine but I wanted a second opinion on the rotor. What do you think?

Hard to see with that straight in camera shot but it looks to me like you have arc tracks on the cap contacts.
With new plugs & wires suggest a new cap & rotor = done deal for many miles.

The caps with the brass contacts are way better then the ones with aluminum contacts..It's hard to tell from the picture if your cap is burned or not , but they're not that expensive to replace both the cap and rotor..WW

Just FYI. I took the cap down to the autoparts store that I use and the owner looked at the cap. The electrodes on the cap were broken! No wonder there was a miss. Got the new rotor installed waiting on the cap to show up. It has brass contacts. Thanks for the help, guys.
