Knock Sensor!

My car has finally recovered from it's sickness! While I have been doing everything possible to fix it including replacing: coolant temp sensor, 02 sensor, fuel filter, hollowing cat, replaced rubber intake boot, injector O rings, cap/rotor, plugs, and many other little things...the #1 problem was ignition related, not fuel related like I had initially thought. It feels like an entirely different car. I don't know what i'm saying, I so friggin happy.
