E90 325i misfire cylinder 1

Hello all,

I am a longtime viewer, but I don't comment very often. I could use some help though. My car is misfiring in cylinder one with the following code:

29CD:
29CD misfirings, cylinder 1
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Signal or value below threshold

Freeze Frame Information

maximum rpm at missfire 1,440.00 rpm
maximum relative load at missfire 99.61 %
minimum relative load at missfire 43.75 %

The vehicle has approximately 88k miles and has not had any engine repair, just basic oil/filter changes. The engine is running very rough, but came on suddenly. I drove the car a few miles in the morning, a few hours later when I restarted the car, this occured. I have restarted it a few times during the last few days to see if it would correct itself, but to no avail.

I have a bavarian technic cable that I have connected to my laptop in order to pull the code. This software can do some wonderful things, I just don't have a clue how to do them. Can anyone give me some recommended steps to resolve the problem?
