Mine's also in MD. Two TSB's were performed on mine (reset distributor
sync and reroute wiring). They told me there's no more TSB's and nothing
else that can be done. High Octane all but eliminated the problem, but
I'm not convinced (based on what I've read in the past) that's a good
idea (reduced mileage and carbon buildup, not to mention extra expense).
If I take mine back one more time and it still can't be fixed, I can
invoke the lemon law. But I wonder if it's worth it for a pinging
problem. Wouldn't bad pinging hurt resale value?

Nope. I don't have any california emmisions on my truck ( I'm in MD) and
my
truck pings too. I'll post the TSB #'s just as soon as I get them so
everyone can check out there problem.
