2010 first issue Random Misfire etc.

I'm new to this forum. I'm usually at the m5board. I thought I'd post my first issue I had with the X. I purchased it about 6 months ago with 48kmi., current mileage is 58k.
A few days ago when I started it in the morning it was shaking like it was misfiring and sure enough as soon as I started backing up the CEL came on and the "reduced power" warning. I turned it off and turned it back on and the car ran perfectly fine. Then a few days after that the same occurred, however, this time it was worse and felt like more than one cylinder was misfiring.
So, I tried the same trick turning it off and back on and nothing the same thing. The it started smoking and I could smell gas coming out of the tail pipe. So I pulled the cheap obd reader and pulled the codes.
Here is the list that pulled up:
I wasn't able to find out what all of them were and didn't really bother searching much as I smelled gas and knew that it wasn't firing on several cylinders. However, I did read a few of the stories with the fuel injector issued and thought that may be a possibility. I decided to try the first thing and check the coils. I have all the records for the vehicle from new and I know that the only thing ignition related that was done was one coil that failed several years ago and spark plugs were changed at about 46kmi.
Before removing the coils I reset all the codes drove the car and checked again this time I only had the cylinder 8 misfire code and bank 1 too rich code.
The firs coil I pulled was #8 and sure enough it was bad. Attached are a few pictures. When I pulled the rest I found that #7 and #3 were bad as well. I decided to replace all of them. Ordered new Bosch coils from rockauto for about $29/each.
Just replaced them tonight, test drove the car and had no issues. It seems like it's running a little better than before.

Hopefully that's all it was!!!!!

well that didn't last long
drove fine for 2 days.
This morning I got in and started it and it was shaking like before. pulled the codes and got cyl. 7 and cyl. 8 misfire.
it's got to be the injectors, I guess.
I'm calling BMWNA tomorrow to see what they say, since the injectors in the 50i are the same as the M and they recalled the injectors on the 50i.
Let's hope for the best.
