Yep, the ping sounds like the valves are adjusted loose if you can imagine what that sounds like. You may be able to get it if you load it against the brake (brake and the gas at the same time) but that can be hard on transmissions and can cause you to drive through the back side of your garage. If you idle along and mash the gas if it is going to ping that's when it will do it. Sounds like you are getting closer. tmm
