Ok, so I finally received my Coil Pack in the mail after 3 months of waiting (due to the virus). I've been driving the car for nearly 2 months with no issues. The mechanic had it and had thought it was the camshaft position sensor and didn't have the tools to test it and apparently couldn't get one easily at the time. I also ordered and received the intake manifold and will have it changed later but it appears that the coil pack was the issue with the car stopping randomly.
It would have been cheaper to order the fix kit and fix the manifold you have, but at least you have figured out what was wrong. Be aware the new manifold could also end up failing as well. Try and remember the symptoms. I reread the posts and see that you are not familiar with gapping the plugs. They are very easy to ruin the tips/electrodes.
Tips to ensure no misfires occur:
Remove the coil pack. If the boots are stuck on, use a small screwdriver or pick with some dielectric grease on it to go around the outside of the boot and then possibly the inside of the boot to help aid in removal.
Remember to (p)re-gap your plugs to .028, (0.24 if tuned)
Set gap with the black portion of this tool.
To increase the gap size bend the ground strap up to the desired height. DO NOT LET THE GAPPING TOOL TOUCH THE
IRIDIUM CENTER ELECTRODE OR PORCELAIN.
Measure the gap with feeler gauges.
Throw this away.
Torque to 18 ft-lbs with no anti-seize on the threads of a stock type plug.
Ensure the boots have no rips/tears or holes in them, lightly coat them with dielectric/silicone grease and make sure the resister springs are clean and not caught up in the boots when you install them.
If the plugs look bad, consider these:
-BKR8EIX-2668 (iridium plugs), ~$25, expect ~10-15k regaps on these, ~40-50k overall life.
-BKR7E-4644 (nickel/copper plugs), ~$8, expect 15-25K out of these plugs, with a regap or two required at 5-8k intervals on stock tune.
