Pinging/knocking
Yesterday I had to stomp on it to get around some bicycles. I hit it hard and notices some slight pinging/knocking at first. What is the cause of this and how do you fix it.

I really don't drive it that hard. I do occasionally get on it but not that often. I don't know how it was driven by previous owners.

I agree with Pounder !!...try some GM Top End Cleaner...I used 2 bottles as some preventative maintenance a few months ago...1 can into the PCV and the other can through the Brake Booster !!...the back of my valves are probably clean as a whistle...none of those pesky P0300 misfires which are difficult to diagnose in that area !!
