I know you checked the pressure of the cat, but what are the reported values between the #1 O2 compared to the #2 O2 when it does this? Knock sensors in the V-6 are hyper-sensitive so it is very possible that it's picking up false knock. I doubt it though, even knowing how sensitive these actually are.
