Default 1993 Chevy Blazer runs rough problem

Not sure why. It's a 1993 Tahoe LT... S10 based, 4.3. (Yep.. spider injectors unit.) This truck is all original and this happened "on the highway, cruising." Sucked an electrode out of a plug..

Here is a video presentation of the problem.

This is my "forever truck," so.

The coil is the one thing that was not changed.. I should probably change it.

The plugs, wires and cap rotor, I should go back to the shop and get the invoice because that's a good question. The wires are ACDelco;The plugs are CR43TS; I'm not sure the cap or rotor.

Injection spider is fun. Did one on a neighbors s10. Thinhg smoked like crazy before but ran factory fresh after. Good luck.

I've heard it best to go with a remanufactured unit, like Belden (NAPA) as I heard ACDelcos all fail the same way..

In any case.. Ignition coil ordered for like 16 bucks, gonna start there.

Im honestly wondering if spark weakened after 22 years. Maybe just maybe it will ignite fuel not presently being ignited..
Is there any chance it could?

I know there is "only one way to find out," but everything past that is a larger repair. (*past changing the ignition coil)

These 4.3s can take a beating, too..

Clogged catalytic converter has been suggested.

My muffler looks destroyed.. had flame shooting out of hole in it when full hot. So.. between muffler and engine is the cat..

^^^ it's a misfire.

Will changing an ignition coil help me? Is it better to test the plugs at the plug, instead of at the dizzy? Does it matter?

Are plugs set on the right order? Any vacuum leaks? Bad spider? The one i did was actually the 2nd attempt 1st one bought by owner was a dud. If you cut the cat off and start it you will see if it behaves differently if it doesn't you can have a muffler shop reweld it with the new muffler you are gonna need anyway. Sorry if its vague info or monday morning hail marys im offering. I feel your pain. I hope it helps in some way.

Might also try a plugs change one more time.. wires seem "perfect" (quality) based on this test i just did.
