Before going to O'Reilly I pulled the two 30amp fuses for ignition 1 and ignition 2, they looked fine other than some minor corrosion where the fuse connects to the block. Replaced the originals, drove to O'Reilly without any obvious misfire, replaced both ignition fuses with new ones, drove back with no misfire. Even turned AC on for the ride back to see if it would cause any change and no issues.
Checking the voltage again going to ignition coil read at 6.5V
Thinking I'll take a longer drive later on after it cools down a bit to see if anything arises.

Happened to speak too soon. I had one short drive with no misfires, but when going out for a second drive had issues immediately. Just my luck that it couldn't be anything simple, so I guess it's time to delve into the wiring and hopefully learn a thing or two.
-
Would it be possible for a bad drive belt tensioner to cause misfire?
-
Not likely, nothing I have ever seen. They make noise that's about it.
How did the 6-volt ignition issue pan out? I would sort out the wiring issues before throwing any more parts at it.
-
Wasn't planning on spending money on the tensioner, just curious if anyone had heard of it being able to cause misfire.
As for the wiring, I soldered in a new ignition coil connector due to the old one having bare copper in a couple places. From visual inspection of the rest of the wire/wires in cluster didn't notice any obvious issues. Wouldn't know how to go about diagnosing any wiring issues other than from just visual inspection as I've only ever taken a basic electrical class and that was a few years ago.
I did have a wiring issue back in December & the shop claimed that the mail wire cluster going into the fuse block was melted into the base of the fuse block. They quoted more than I could afford to replace the two parts at the time so instead they ran a line from the positive battery cable into the wire cluster through a 100amp fuse. This negated the need for having the 50amp battery fuse in the fuse block, but while I was looking through the wiring I couldn't find anything resembling what they were talking about.
Unfortunately I'm unable to sell the vehicle due to a lien on the title so at this point, I think I'm just going to use the vehicle for local short distance errands until it dies.
