When you say knock are we talking about a Ping of sorts?

How is the oil pressure? and is it stable?

It has that too, but it sounds like it is igniting too early, pinging, knocking, take your pick of terms. Premature detonation?

Premature detonation can cause engine damage. You need to check the plugs - now.

Also might want to check your exhaust manifolds for cracks.

well, scanned codes, got this:

12
23
66

12- normal
23-IAT low
66-Refriderant Low

I guess that does not shed any light on anything :(
