The knock goes away when one of two things happen; I reach the speed I want to go or I let off the throttle (a little) and accelerate slower. This is definately not a shifting too soon issue, but I'm not trying to wring it's neck either.
What octane are you using? Is it too high? What's in your tank....
The other day I saw that the price of gas went down in the area and I said, oh he11 lets be nice and put the next grade up from crap in. Big mistake, knocked on hard acceleration. Burnt that tank and put low octane in. Wow, no knock..
Put some 87 in and I bet it goes away.....
