Bull thanks for sharing your theory. Are you recommending not using K&N filters?

I wanted to wait till crossing 1,500 miles before I posted. P0174, the only code consistently coming back before I replaced factory MAF's, have not come back and car has been running well as before. However U1000-01 CAN COMM CIRCUIT has come back 3 times consistently after clearing message but only when I run OBD Fusion, not as an engine light message. SonicVQ how can I dig deeper as to what may be causing this message?

In short factory MAF's seem to have taken care of my original codes.

Report attached.

Also I never replaced upstream O2 sensor, which was part of list of potential culprits on that list for P0174 fixes, but wondered if cleaning or replacing upstream and downstream O2 sensor would make the car run better.

bjmsam steam up front was how I found that connector busted. Seems like that's not your problem hopefully you fixed that. Nice 165K! I'm looking forward to continue enjoying my G.

I have encountered zero problems since replacing those blown filters, now with 170k. Thanks!

The "Intelligent Master" is the old name for your AV control unit (aka radio / nav unit)

You could use the built-in "DIAGNOSIS SYSTEM (AV CONTROL UNIT)" as shown in the FSM, section AV.
(If you don't have the FSM, you can download it for free at nicoclub.com)

*** DO NOT SELECT "INTIALIZE SETTINGS" OR YOU WILL NEED TO GET THE DEALER TO REPROGRAM THE AV UNIT ***
The "Vehicle CAN Diagnosis" menu may give you a hint as to which module isn't communicating

Another option might be to disconnect the battery, remove the trim to get the radio out (not difficult) unplug and plug in the connectors on the back and reassemble.
That's all I got
