You have a bad KS. I would change them both, make an RTV dam around the knock sensors (GM TSB), and replace the wire, while you're at it.

no, but performance will SUCK

you're most likely in the low octane tables right now... and getting timing pulled out on top of that...

pickup some new sensors, do the RTV damn as suggested (do a search here and there are instructions for it somewhere)

it's not a big job... gotta pull the injectors and the intake manifold, then the knock sensors screw into the lifter valley cover under the intake manifold

Exactly.

And when you put the intake back on, be careful you don't crush the KS wire. Route it just left (looking from the front) of the knock sensors, but keep it away from where the intake seats. Also, don't forget to pull out the foam square under your intake (it wicks water under the intake).
