That's what I thought as well, expected to see the warning light on the dash as well as the code, but nothing. The pinging noise only occurs under the condition I described in the above post. The engine is very quiet and smooth otherwise. It is actually quieter than the Z which has less miles.
This has been going on for awhile and we have tried every single brand of gasoline available. The engine is stock.
As for the MAP sensor, can I clean it with MAF cleaner? Looks like it is held by just one screw?
