So I only ever drive in Advanced. The other settings are there for when I go over a crappy section of road.<p>Recently, in my sisters VR that I've been borrowing, the damn thing has been backfiring on rev matched downshifts. Or for that matter, any revs at all.<p>I just ran into a friend and decided I'd have him check it out from the outside. I turned the car on and tried it and nothing happened.<p>Turns out it's because I was in Sport. I hit advanced and the first time I let the car get to ~4k rpm and then engaged the clutch it snapped. Quite loudly too.<p>No CELs or other crap though.<p>Thoughts?
