So, I have the pedal box off of the car now (man, I don't wish that task on anyone!). I'll clean it up, replace the bushings and springs, and lubricate the areas needed. One of the casualties in the process was the outer rubber insulation cover. It was very brittle. My guess is, this box has never been worked on. Anyway, is this insulation cover vital? Do people put them back on? There is also a small rectangular opening on the box. This one had some sort of tape on it. Is that normal? Or is there a rubber gasket that should be there, in addition to the outer insulation? I'm not looking forward to putting this back together. But, once it's done, it's done. The next thing on the list is to deal with a severe low idle issue while cold. Once it warms up it's fine, but when it's cold, it idles so low that it dies.
