Knock Sensor Low input code

Hello all,

I've just purchased my 3rd TA. 1998 WS6 and it's throwing codes.
It is throwing the Knock sensor low input code and the car is running rich. The guy at autozone didn't specify which bank.
So I took off the manifold, replaced both knock sensors with Delco ones and put it all back together.

Well the car ran great for about 1 hour, then it started running rough again with the same code :(

The connectors looked ok, but one had a little bit of fluid on it. Could this be a bad knock sensor connector or something else?

Thanks,

I did some searching and I looked at other posts, but I'm not sure on the end result of what they actually found to be the problem?

What was the actual code(s)? They should've been able to tell you if it was the front or rear sensor...or maybe it was P0325 Knock Sensor Module Performance? I'd visit gearchatter.com and look them up for your year.

The code it threw was P0327 - Knock Sensor 1 Circuit Low Input. Just had it scanned again today.
