Hello gentlemen,
I was driving to the gas station when my car died. I limped it home and plugged the ODB scanner in. I am getting a code read of 0301, and 0301 P. The book that came with it tells me this is "cylinder misfire detected". What could be causing this?
Thank you in advance for any advice.

There are many possible causes of a misfire but a single cylinder misfiring will not cause the car not to run. You would have to go back to basics to determinee why it won't run.
All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

I should have specified that by limped it home, I meant it does still run. It died, I restarted it and drove it home on presumably 5 cylinders. When I came to a yield or stop I had to shift to neutral and give it gas to keep it from dying again. Sorry for not being specific.

How about an engine size, mileage, history of past ignition parts replaced?
I assume your check engine light was flashing. That is done so that even the most naive driver would know to stop driving the car because you are doing severe damage to the catalytic Converter. Flashing red lights mean STOP and call a tow truck.

3.2 v6, 137,000 miles. I bought it with 100k on the engine so I cannot speak for anything replaced before that. I have replaced the vehicle speed sensor, changed the oil every 2000 miless.
Yes the engine light was flashing. The gas station it happened at is two blocks from my house, I am not naive. I don't have the money for a tow truck for a two block ride.
I went to autozone and bought plugs and coils. I am going to try that now and see if it fixes the problem.

Problem found.
When I removed the coil pack and insulator the spark plug came out with it. The threads appear to be shot in the block. I cannot thread in a new plug, it just spins in there.
Options?

I bought a helicoil thread kit. Worked fine. Go ahead and delete this thread if you like.

I hope you had a way to get all those metal chips out of the cylinder.

I did. I used a bunch of grease on the tap to catch most of it, and I used a shop vac with a little hose duct taped to the end of it to suck anything else out. I ran it around inside of there for a good 20 minutes.

Not a bad way to do it and glad it worked. If you have to do one in the future it helps to have a borescope to physically look into the chamber to verify it is clear. I'm not sure if you can rent them at parts stores or not.
