My car did some huge bucking when I put in some "premium" (on a trip) that was
more like regular - when the boost hit about 1.4, big detonation. I'm surpised
that I didn't bend a rod that first time I stepped on it since I totally wasn't
expecting that to happen. Did you recently fill up at a gas station that isn't
your normal one?
