Are you filling up at the cheapest place in town, or running brand name petrol?
Just the first possibility that popped into my mind.

Could be a connection, wire, or sensor...can't remember where the knock sensor is, or if I ever knew...
It's that pesky age thing...

ya the O2 sensor isnt that big of a deal, ill fix that and im sure it will fix that one...its just the knock sensor i dont know about...

not sure why you are throwing the code but from my understanding engine knock is premature detonation of a cylinder (go ahead and chuckle) its usually caused by bad/poor quality gas, the octane rating is an indicator of the knock resistance of the gas (89 is more likely to knock than 91) so i would start by clearing it and running some fuel system cleaner through your gas and see if that helps

alright ill try that... i always use premium, but in greeley (its a ghetto town) that doesnt always mean a lot...
ill run some STP injector and fuel cleaner

Any station can pump some crappy gas through their pumps, especially from the bottom of the tank (did you notice the pump running especially slowly?). You just never know...
The knock sensor is often mounted directly to the engine somewhere on the head (may be difficult to get to). It senses the premature detonation etlsport described and retards timing if it detects consistent knocking. I would see if you can find where it mounts and clean up the connection or replace it if you are highly motivated.
The second fault is the one to focus on for now - run the cleaners through your engine and some good fresh gas and see if the fault comes back.
Good luck!
