I have possible misfire, or tranny slippage.

What is your question?

What could be causing the misfiring? I have an 07 bmw 530i with around 186k miles. Just recently it started acting funny. Whenever I take off from traffic lights or start entering a highway the engine will start to misfire, or so I think it is, and shake. It does it from around 1500-2000rpm. What could the issue be? Spark plugs, wires, or coils is what I'm guessing but I'm not sure. Can I please get some help!?

This is more of a ignition coil, taking off from a stop , demands more ignition secondary due to the load, a failing ignition coil would not be able to keep up to the demand, Gather a diagnostic trouble code, this would help pin point what cylinder is offending
