Took her to my indy mechanic and replace the thermostat - t'was bad.

Drained and flushed my coolant, so it's now at 50/50. I wasn't even thinking about the coolant mix before I went up there!

Disaster averted!

I must have blown out a good deal of carbon on the ride - she's running better than ever.

thanks, guys!
