RPM Stumble while idling
 

Vin: 4USFE43517LY78582
Chassis: E70
Model: X5*3.0si
Engine: N52B30O1

Swapped Plugs out and now having somewhat of a random stumble in RPM while idling.

Ran ProTools no codes
Logged live data
The stumble seem to happen consistently every 45 sec or so

Setup logging for the 6 cylinders and looks like #2 is the issue. Thinking Coil in #2 is on its way out

The PDF is the RAW data from PROTOOLS. If you look at the RAW data you can see the jump both time in #2

Time Stamp: 10.167 & 33.935

Drops to -14.89

Not sure what the range represents, assuming that if I go back and correlate the order that the cylinders fire
1-5
3-6
2-4

Thoughts?
