I posted a week or so about the P0327 knock sensor code, and was prepared to change them, but I have cleared the codes a couple of times and the car will run for a day or 2 before setting the codes again. What, i am seeing is that the P2105 is always set along with the P0327 code. The engine performance does not seem to be effected, so before going down the knoock sensor rabit hole I thought I would see if anyone else has encountered this combination of codes.

Sorry, 2100 series codes were not introduced for engine controls until 2004 to the best of my knowledge. Even with that, P2105 not one I'm seeing for GM. Have you had a PCM or Engine change? Or perhaps you are mistaken on the code P2105?
My appologies; it is a C2105 code along with a P0327. That is a tire sensor malfunction. That would explain why the code was not in any of my shop manuals.There is a P2105 which I had googled and it is a Throttle control error code which is what i was expecting. Thanks for having me go out and re-read it. So it looks like the main issue is still the P0327.

Don't think your 2 DTC's are related but where did you purchase your currently installed knock sensors ??...Amazon or Ebay ??...if either one of those that part may be suspect especially if a Dorman part...you can check for the resistance between the harness and ground which should be 93-107 Kohm's...were they torqued accurately...11 lb ft ??...you may want to check the circuit between the PCM and knock sensor harness for high resistance especially at the PCM...Pin 51 (dark blue) on the C1 connector...these piezoelectric sensors produce a very small current so you want to make sure you have clean connections....do you like Pete and Elda's ??...miss their pizza.
