Default CODE P0327HC Knock sensor?
Had a PCM 10 code PO327HC with check engine light on. Car does not run very well or wind up well with light on. Do I need just to change the Knock sensor? If so where is it located? And I assume the bad performance is due to this code.Right? thanks

There are 2 knock sensors UNDER the intake manifold.

It doesn't get much easier. I guess you've never had to R&R a SBC intake.....much more work involved...

Seriously, no manifold to seal up...no water leaks, vacuum, oil leaks to worry about. No dizzy to mess with. It's really quite easy.
