Pre-ignition or detonation, which are what are commonly meant when using the word "knock", don't happen unless you're accelerating. If your car knocks when you're not accelerating, you have some mechanical problem like bad rod bearings, piston slap, slipped timing belt, etc... Quote:
I have not replaced the plugs or ignition coil. Would either of these give me a knock? I also want to try replacing the knock sensor if our car has one.
None of those things will address the mechanical issue it sounds like you are having...they can only address pre-ignition or detonation related issues...
If you're not sure how to tell the difference between a detonation knock and a rod bearing knock by listening to it, then you should probably bring the car to a competent diagnostic technician and have him/her listen to it...then you'll know what direction to go in...otherwise you're just throwing parts at the problem.
