If it is the distibutor cover, you have to remove the w/p and the harmonic balancer......

If you just replace the w/p, and still have the misfire, and it turns out to be the cap, you end up doing it all over again(w/p).....

this is just like when Firebirds needed complete turneups, and you gave the customer the estimate, and they almost passed out......I would always recommend a new w/p(I just want a tuneup, why are you replacing my w/p?), if it had never been replaced, because you don't want that old one put back in and then leak on that new cap....

Just like the Roadmaster, the plugs and wires are a nightmare....

So since you have a misfire, you have to ask yourself one question:"Do you feel lucky, punk?"
Always great to get help and a good laugh at the same time.

I'm guessing its the distributor cover, exacerbated by the fact that the w/p is leaking. My guess is based on an incident where the car was driven through a puddle of water and started misfiring. I suspected arching and tried spraying down the engine at night but didn't see anything.
