I picked up a 98 ws6 a few days ago and trying to diagnose some issues. I had a CEL and got the codes pulled. Was an o2 sensor, and knock sensor. I was driving the car on the fuel they had in it (87 octane), and was wondering. Could that cause the knock sensor code? I filled up with 93 today and drove the car. Seemed to have cleared up a bit, but some hesitation is still there. Is it possible that was the issue and running a few tanks of 93 through it should cure the issue?

the wells where the KS are fill up with water......rusting the KS and corroding the wire harness.......get a new 99 (00?) and up KS and harness..........the 98 was a bastard yr and the newer parts will fit

Gonna bump my own thread with another KS question. Is there any difference in the 99-00 KS and harness and the 01-02 KS and harness? Im gonna just replace them both and the harness and RTV around the holes to keep moisture out while im in there.

Nope, 99-02 are the same, 98 is different.

No problem, i just ordered mine too. I got em from rockauto.

Wow thanks for that heads up on rockauto. Thats 60 bucks cheaper buying both through them even with the new harness. Are the part numbers for the front and rear both the same?

Yeah, ACdelco part# 2133521 for each of the sensors, and part# 12601822 for the harness.
