Sorry dont mean to hijack a thread here....

Ya, I thought it was the knock sensor so I wasn't to worried about that thought I would mention it though.
If I had to guess, I would say lower end, as it is slower than engine speed, I thought of a rod but it doesn't make sense, as it is not consistant enough. If it was a rod going under load then it would do it pretty much every time you loaded it up, not only once in a blue moon, oh and if you floor it when it is knocking it goes away (forgot to mention that) I have been avoiding the pulling the heads part
as I am thinking that way myself, but it is a lot for a car we are getting rid of and isn't worth anything
