I don't know what it is but I know theres a different type of one on my '93 this one is on my G/Fs '92, is that what your looking for ??

That could be it.  Is that an ignitor, noise suppressor, or
what?
BTW, while I'm getting a pretty good spark at #1, #s 2, 3, and 4 seem minimal at best (#3 is almost non-existent). So, fuel flow seems fine, but spark may be in question. Would that part or any other cause poor spark? The dist & rotor are good. Wires are good. I tried an old (know good) coil and old plugs.
