on my 98 vette the dealer installed new factory knock sensors also replaced the harness and had the computer gone over! the knock sensor codes still appear and the car has 33k and runs like new with no noises from the engine any ideas on maybe some soft ware to the curciut on the computer
 
Have you reviewed the diagnostic information in the Factory Service Manual for those two codes?

It could be anything from using aftermarket knock sensors (yes, dealers can do this out of warranty), over tightening the sensors, bad pin fit in the harness connectors, poor ground, harness routing, etc.

What does the dealer state as to the reason the codes are appearing?
