SES light comes on flashing, then disappears by itself an hour later...
I got my first SES light since owning the car (approx 6 months now) I went to start it up in the morning and the motor was running roughly, so I decided to go around the block to make sure everything was okay. Then, all of a sudden while driving, after some weird jerks, the SES light just starts flashing over and over, then eventually just stayed on. I got the codes read and got 2 counts of random cylinder misfire and a power steering sensor failure. Then, after driving around 5 miles, I started the car up again, and it was just gone.......
Should I look into this more? It's more than strange

I've had the same thing happen 3-4 times randomly now ever since I replaced valve covers and new plugs. I am running @ 160k+ miles on the coils/wires.
I'll just drive until the coil(s) actually goes out, if this is in fact the issue.

Or so I've been told. I'm no mechanic.
However, ignoring a problem is a valid option too.

If a coil pack isn't functioning, that means un-combusted fuel is getting blown out the valve and likely burning as it goes through the heated elements in your catalytic converter, which can cause your cat to overheat and clog.

My point is, you could easily spend a cool $1000 with what seems like a simple maintenance item.
Or you could identify the errant coil pack, replace it (with a 50:50 chance it's in the front bank), and walk away.

Coil packs cost between $80 - $110 each, depending on how you purchase them. You have six, which means $480 to $660 in parts. Figure another $50 for a new 6.0 gen rear valve cover & gasket, and another $50 for a set of plugs, and then if you go to a mechanic and incur 2-3 hours labor...

Had that happen after my car sat a couple weeks after it was hit and totaled. I had been starting it to keep the battery charged since when the adjusters do the estimate, they need to see what the mileage is. Anyway, I started it up and it was running really rough. Got a misfire code and a power steering sensor code. Cleared the codes, restarted the car and it idled and revved fine after that. Not like it mattered much, wasn't going anywhere with how badly damaged the car was.
