    Avoid non GM knock sensors. I bought some on eBay once that caused the codes to come right back. Replaced with GM and codes were gone.

    Don't know of a full write up but here is a video of someone working on the knock sensors. Should give you an idea.

    They make disconnect tools. There are four tabs inside the fitting that need to be depressed to get it loose. I usually just use a pocket screw driver to work the four tabs back on at a time. It will take a while on your first go but you will get better at the fuel lines after a couple tries.

    Don't reuse original intake gaskets on a 2002. The orange ones are fail prone to vacuum leaks.
