Where is the knock sensor on the 3sgte and how is it to replace? If someone has a picture that would be great

Sorry, no pictures at the moment, but it is under the intake roughly centered on the block. You cant miss it. Look up from under the car. It'll look like a single sensor with a large hex and have a round plug comming out of it (IIRC the plug is green) and have a single wire (Oh its a shielded coax wire btw).

Ok, do you have to take off the intake manifold to get at it, or can you just reach from below and remove it?

You should be able to get to it from below...

Oh, I forgot to mention its centered towards the top of the block just below the head mounting deck surface..
