My MAF sensor I believe was cutting in/out or missing/ bucking action somewhere around 4K.

We cleaned it and the K&N and we ODB linked it to a laptop and went for a drive and found the MAF was the culprit.  

We proved it as it disappeared with the MAF installed. 

 

P.S. The K&N one time was dirty as well as the MAF and causing it to have this symptom.  I think this should be cleaned with each oil change IMO.

Meanwhile...

Make sure you don't over oil the K&N filter on a MAF equipped engine.  The extra oil mists the MAF sensor wire and cruds it up quickly.  I discovered this the hard way, and found it mentioned heavily in forums on my old Turbo Volvo V70 and my current MINI Clubman S.  Some were hopping up and down on their hats yelling, "NEVER use a K&N on this car!" But I found that just being reasonable with the oiling made it all fine. Adding a quick spray with MAF cleaner at every oil change sounds like a good plan.
