The car only has 33k, sensors worked just fine until I swapped the LS6 IM and now both of them are bad...? What to do? Any suggestions before I have to take the IM off again?

Unplugged knock sensor wiring harness, damaged wiring harness.

Its pluged in, I checked that first! Damaged? Idk, maybe but I really dont want to take the IM off again...

Probably best to pull the intake and replace both sensors and the harness. Be sure you use a torque wrench to tighten the new sensors or they won't read properly. I'm guessing you disturbed the wiring or sensors. Also the new intake may have damaged the old harness. Its fits differently than the LS1 intake on the bottom.

Did you grinD off the fins on the bottom of the LS6 Intake? If not you probably crushed the wires to the knock sensor
