I have this exact Berryman kit on top of my tool box. I am waiting for Linda to get back from Texas and she wants to be here when I do the service. Her engine is 24 years old but only 78k miles...
I like to start with basics. Age and miles on the existing plugs? Plus, like @budwich and @dhanger alluded to, please answer about the kind of driving you do. Live data scanners are not that...
And I'll take that idea one more step down that "Fundamentals Step Ladder" and start with the "Big Three of ALL Four Stroke Engines"
(1) Fuel
(2) Air
(3) Spark (Compression)

Sadly I had to let my 2006 Trailblazer go. I was wanting to rebuild it but haven't had the time or money to do an engine and transmission rebuild.

Unfortunately, it looks like the ACDelco TEC is no longer available. However, the next best "Chemical Analog" for doing this Top Engine Carbon Busting Job is:

I am now considering doing the AC Delco top end cleaner and getting the live OBD2 reader to check the misfires, timing changes, and fuel trim readings.
But I can't seem to find the "ACDelco GM...
Actually, I think this code (and related sister code) means that the system will not being doing its job as the system disregards the output from the sensor and thus there is NO compensation done...
Here's the schematic for the knock sensors. You'll want to check the wires for sensor #2.
Be sure to check resistance/continuity from the sensor wires to the PCM and also to ground on both...

Have you actually looked at your misfire counts?
There are likely other things associated with actual firing issues that would show up if you look at fuel trims.
EDIT:
A Correction and Admission of Error needs adding ahead of this Post. Thanks to the follow on Posts by @budwich and @Mooseman after this one which informs My Mistake in the idea that the...

If your tune also included a delete of the codes for the EV fan clutch, you could get a regular thermal clutch for a 2008. The EV clutches are so bad that even GM went back to the old fashion...
why did you pull the radio? Maybe there was some "back feeding" happening for voltages and when its gone, so is the "back feeding".... maybe check fuses.

Happy to report that I was able to piece the broken bracket together. Glued and then I used a hot stapler from Harbor Freight to strengthen the plastic bracket. Fender and bumper went together...
The intermittent shutdown at idle shortly after startup during driving happened to my truck recently. It was the cam position sensor on passenger side head that lost its place after driving a...
Thankfully "The Auto Teacher" gives clear and concise instructions for the code and the part replacement steps. I have done videos at you tube, some for the 2002 Trailblazer Linda owns. I tried to...
That's pretty classic for a stepper motor failure. When some of mine failed, they'd twitch up a little bit when they were supposed to do the sweep, then just fall back, usually below the zero...
That may be stepper motor failure? I cannot say for sure as I have never personally seen stepper motor failure. When the key is first turned to RUN do the gauges all sweep counterclockwise towards...
