Mine hasn't done anything wonky like that, but checking the grounds does have merit, as the body is fiberglass, the grounds are even more important.
Mine is a '94 as well, and I have the factory service manuals, all 2000 pages worth. If you want, I'll look through the troubleshooting section and see if I can find anything that will help! If so, I can easily scan and email you a PDF.
The '94 has 7 separate grounds as I recall.
Anyway, let me know. I'll look and see what I can come up with.
