Bad couple weeks for the Boxster

I get the feeling that these things are linked. Hip bone connected to the thigh bone...
Just a hunch but when my car blew a smoke bomb at the track a couple of weeks back, steved0x mentioned that a slight oil overfill had caused the same situation with him. That event threw a code saying "cylinder misfire could cause damage to catalytic converters". I think that blowing oil through the system is generally to be avoided.

Oh BTW, I picked up a used primary cat of ebay for cheap. Works fine.
