Spark plug pic's

[Bruce]

If you can actually hear pinging, on a newer car, there is a huge problem.
Up the octane level a few notchs, if your wanting to keep the car.
Not all detonation, is audible.  You can run trace, and tip in detonation,
and never know it.  Do you know what detonation detection strategy Toyo
uses?.
