Hi, just like the title says I've got spark knock. I came to this forum with this problem at 35,000k miles and now the issue is back and I'm wondering if anyone else is having this problem. I specifically hear the knock at about 3200rpm in sport mode. I've switched to mid grade gas and the problem persists.
My preferred dealer says there are two valve cleaning options available. One is a solution that is administered through the manifold and the other involves removing the cover and scrubbing the valves and cylinders with a brush.
