Default Problems after cleaning valves - 05-06-2014, 02:02 PM

2010 535ix jb4
I'm having alot of problems with my car.
The codes im getting are
2acc DME main relay, switch
29cf misfire 3
29ce misfire 2
29cc serveral cylinders misfire
0000 unknown fault.
The misfire only seems to be at idle. If i restart the car sometimes it will idle fine. The problems only arose after cleaning the intake valves.

Maybe I bumped something loose? Would a bad battery cause this issue? The dealer I got it from is going to replace the battery but I don't want to drive it with something major wrong.
