So my SES light just came on and when I scanned it, the scanner said it was the knock sensor. I heard there were 2 knock sensors and they're under the intake. Is that correct? My 97 LT1 had it right on top of the intake manifold. Thanks guys.

 

Yes under the intake. http://mycarpics.shutterfly.com/198 The 2 holes in the gally cover.

friend had a knock sensor code, and after inspecting them and hunting for over a month i just waited till he wasn't looking and broke the top off both of them while the intake was off and he had to buy 2 new ones. Code has never come back
