If I rev the engine slightly for a few seconds, it seems to go away.
Could also be the fuel, but I pretty much use Shell religiously and am at about 17k miles. Never used the techron formula, but probably should throw a can full in to see if does anything. Can't remember if this happened before they installed the PPK, as well, or just after.

Thanks. I can't remember it before the PPK either.
Will just keep watching.
