Probably a knock sensor going bad. They are cheap to replace.

did you wash or degrease your engine recently?

See if it's still plugged up or a wire gone bad.

Knock sensor number 2. I believe thats the rear one. You have to pull the intake manifold off and check them. They usually get water In there and they rust and go bad... search the site there is a thread about how to fix it.

this is such an exhausted subject, but heres my 2 pennies

If ya got a lot of excess water on your motor it will gather on the valley cover where the sensors are located and short them out. Knock sensors are nothing more than microphones listening for detonation and adjust timing as necessary...blah

Anything worth doing is worth doing right, right? so replace both sensors and harness, you"ll need intake manifold gaskets too. To fix it, without being patient, will cost you around $200.

It took a month before my sensors started to work again, dont know what your situation is, but more info would be nice.

My LS1 has over 270K on it, knock sensors are still good to go, just sayin...
