knock sensor corrosion?
Put another manifold on today and it seems my hissing on the highway at load in 4th has gone away. So I assume I cured some sort of air leak. Anyways, at WOT I'm still getting the damn 8 degrees of KR. I'm fed up and about ready to find a new hobby. While I was there I did happen to peak at the front knock sensor and see it corroded and some on the wall too. I couldnt see the rear sensor. Can this cause knock like I'm getting? I dont hear a DAMN THING like knock at WOT. I apologize for the poor pictures (Iphone)

I would replace them both. I just replaced both on my 01. my front looked fine my rear looked x50 worse than yours. I also had about 1/8" of water and rust sitting in the cavity of the rear. I sealed the top boot with high temp rtv. to keep the water from getting back in.

Either way you're eventually going to have to replace them and build a dam with RTV (there's a TSB in reference to knock sensors corroding, check it out on your AllData). It makes sense that the knock sensors could be sending false signals considering how corroded they get. I *think* that there's a sub-harness to the sensors that you'll probably want to replace also.

People drove cars for years without knock sensors and they never blew up. I have a hard time letting the computer control certain things that I don't wish for it to control. Such as disabling the IAT spark tables and anything else spark related that's not coming directly from the spark table. If it's 150 degrees out or 150 below, I want to be in charge of the spark tables, not the PCM. I'm old school I guess......
