Suddenly Tons of Codes...
Today was a very strange morning...
I got in the truck and it started perfectly. It ran smoothly until I was ~3 miles up the road (engine was warm by now). All of a sudden both my M ans S LED's are flashing (along with the D on the selector) and the dashboard is 'dinging' at me!
OK, I mutter a couple of expletives and pull to the side of the road and shutdown. I mull on what just happened for a moment and try the key. It turns over (fast - lots of battery juice) but no fire. So I pop the hood and hit the inertia switch (it gives an audible 'click') and try the key again; she fires right up!
So I am feeling pretty good about myself and I carry-on up the road and stop for gas (Shell Premium). I then carry-on my way to work. All is looking good, sounding good, feeling good - no issues... 6 miles later the CEL comes on! What the F!!!
Well, there was nothing to do then; middle of nowhere without a code reader and the truck is still running smooth (not even a hiccup). So I carried on and checked the codes when I got home tonight. This is what I found:

Well, there was nothing to do then; middle of nowhere without a code reader and the truck is still running smooth (not even a hiccup). So I carried on and checked the codes when I got home tonight. This is what I found:
- P1300 - Random/multiple cylinder misfire detected - Catalyst damaging level of misfire on more than one cylinder
- P0304 - Cylinder 4 misfire detected - Injector 4 excess emissions/catalyst damaging level of misfire
- 0305 - Cylinder 5 misfire detected - Injector 5 excess emissions/catalyst damaging level of misfire
- 0307 - Cylinder 7 misfire detected - Injector 7 excess emissions/catalyst damaging level of misfire
- 0308 - Cylinder 8 misfire detected - Injector 8 excess emissions/catalyst damaging level of misfire
- P0335 - Crankshaft position sensor a circuit malfunction - Reference mark outside search window for more than two revs, with engine speed above 500 rev/min
- P0300 - Random/multiple cylinder excess emissions detected - Excess emissions detected on more than one cylinder
- 0304 - Cylinder 4 misfire detected - Injector 4 excess emissions/catalyst damaging level of misfire
- What single cause could be doing this?
- Was the incident with the inertia switch related to CEL incident?
- Was/is there a single cause for both?
- Are the codes above a possible result of a bad tank of gas or are they related to the CPS? (if CPS was bad, I didn't think the engine would start)
- Am I possibly having an electrical issue that is causing all the symptoms?
- Is there some other answer possibly involving aliens?
