Default Knock low rpm 2k-3k light load

I am having some issues with my car and was wondering if a popping strut could throw a false knock?

I just found out a damaged O2 sensor can cause the same problem. So I'm retuning for 100% open loop since i don't want to buy new O2 sensors every week.

So if the MAF turns out good, check your front O2 sensor.

Yea I think it is going out too. When I was logging I.saw inconsistencies in both the o2 and maf and opted for the maf first.
