Okay guys, I did the seafoam tonight after work. Didn't get any smoke after the let sit and start up time period so, I took her out for a spin. When I was cruizing at about 45-50mph and stomp on it to get the passing gear to kick in. The first few times I was still getting some pinging but, after doing this a few times and a little less stomping but, still kicking into passing gear, I was getting less pinging. It only did it when I kicked it into passing gear. Maybe I just need to take it out on the highway more to blow it out some.

Any other ideas and options please fire away.

Thanks for all the help.
