StevenC You could have another issue causing a problem and making the engine ping setting off the knock sensor. Like a chain reaction it will all go down hill. I personally never have seen a bad knock sensor.

spankys rod shop I gotta go for now but try to find someone with a tech II scanner with a good understanding how to use it and i'm sure you'll get to the bottom of it.

spankys rod shop I guess there is a first for everything, I've never personally seen a bad knock but its verry possible, the effects of a bad knock sensor could vary like timing retard and such. But there are 2 knoc sensors screwed in to the knock sensor plate which is located under the intake, they are pluged in to a small harness that leads to the rear of the intake, its a small plug mabe you could just un-plug and plug back and try scan again or re-boot comp. what is it acting like?

spankys rod shop You should find (2) just under the intake manifold with the plug in the rear. one plug on a small harness that leads to both sensors.
