Car freaked out

[TX135i]

Last night I was sitting in a traffic jam due to a jack knifed semi for about 45 minutes at least. Literally in Park most of the time, nowhere to go. Car was idling fine, oil temp was right where it should be. When I got close to an exit to take a detour, I put it in drive, gave it some throttle and it started popping and bucking like it was running on three cylinders. Half yellow engine light came on and the blinking SES light came on. Car would barely accelerate and sounded like a lawn mower with a carburetor problem. I could eventually get up to speed but it was shaking like a dog crapping a peach pit. Drove maybe 10 miles and it never got better, but I found a McDonald's to stop at. Went inside, came out, started it up to see how it sounded, and it was perfect. No lights, no pops, it was 100% back to normal. This morning, still normal. Going to read some codes but it was the damndest thing I've ever seen.

A few weeks ago, I changed plugs and chips. It started misfiring like crazy. Shaking like crazy, no power.

But turn it off and back on, would run fine.

Swapped things around, it ended up being a bad plug.

Well, I checked the codes and there were many. 2C01, 2BF8, 2EFE, 2EE0, 2F02, 2EFF, 2EE4, 2EED, 2F01, 2EAA, 2D22, A6CF. I'm no expert but it looked like maybe a high pressure fuel issue, and some oxygen sensor issue. Maybe one initiates the other. Still running normal now, but I dont know if it will likely recur and if I should take it in now, or just see how it goes.

Actually my mini hpfp was like that. Left me limping down the tollway, pulled off, restarted it and made it to the dealer just fine. Forgot all about that. I would definitely take it in with the codes so you don't get stranded.
