Nice find. I see you are getting KR (engine Knock, Retard the spark timing) everytime you use the throttle.
Not sure if your knock sensor needs to be calibrated and it is giving you phantom knock or if it is real knock.
Is it running on low octane fuel? How old is the fuel?
The knock sensor is below the oil filter.
Did you touch the knock sensor? It is suppose to have the wires leaving the sensor at the 9 oclock position, and be torqued to 18 ft lbs.
I can't find a "Chevy" way to recalibrate the knock sensor... but HP Tuners allows changes. Post #16 here.
