Ok from what I have read the sensor itself rarely goes bad. Several other things besides wiring can cause the 34 code. O2 sensor, bad gas, ground problems. I think you are headding in the right direction by checking wireing first. In trouble shooting I find doing the cheep stuff first helps keep cost down.
Ok, so as far as gas goes, I always get the cheap shit...

And acording to the previous owner's records, he had this replaced
2/18/2008 - $556
#1 Replaced MAF Sensor
#2 Replaced PVC Hose & EGR transducer
and then this
11/17/2008 - $611
#1 Pass smog
#2 Replace O2 Sensor
#3 Replace dist cap & rotor
#4 Replace ignition wire & spark plugs
Is there more than one O2 sensor?
and recently I replaced the fuel filter, spark plugs, and did an oil change. All that made a huge difference along with the eBay 3" catback. When I was under there last to put the cat back on, I noticed a wire flopping around, and I thought nothing of it, as it was probably a ground wire by the looks of it. You think that might be my problem from the start? After all this everything has been going down hill at a 90* angle.
Either way though, I have a new knock sensor on the way courtesy of eBay, so I will know more soon.
Thanks for all the help and suggestions thus far.
