Hmmm, sounds like the problem I just went through. Took me a while to figure it out. If your distributor cap isn't AC Delco OEM, this will happen sooner than later. Autozone caps are the WORST, won't last very long until you have internal arcing. By the way, other brands including Autozone seem to work fine, in OTHER vehicles for me. This engine needs to have AC Delco Plugs, Cap, and Rotor. After replacing with a new cap, does this problem disappear for a while, then come back? Also, make sure the cap is screwed down correctly, use a mirror for the back screw. And finally, double check that the PLASTIC screw tabs on the distributor are not broke off, causing your problem of not seating well or tight. If your are broken (VERY COMMON), only Napa makes a distributor repair kit. It's a metal arch, that attaches from the bottom of the distributor, then the screws in the cap thread into this. Hope this helps, it eluded me for months.
