03 Sierra P0332 4.8L
I looked at some you tube videos on replacing both of the sensors under the intake manifold. Not a fun job but its got to get fixed.
Parts list so far 2 knock sensors Intake manifold gaskets Here's a few of my questions. Should I replace the intake manifold bolts? The video says to replace the knock sensor harness also. Is that necessary? Which KS harness? Rock auto has numerous to choose from. Code:

I would repl.the intake bolts, they are torque to yield. Check for tsb's on the knock sensor codes for more info.
