I would say your heater circuit in your primary o2 is shot. Replace it and it should fix the p1166.

For the p0219, check this out : http://engine-codes.com/P0219.html

Do you Ricer Rev a lot? lol
Pull the 15amp ECU fuse in the under hood fuse panel, wait 30 seconds and put it back in. That should erase that code.

Sounds like you missed a shift and had a mechanical over rev.

As mentioned above do a ECU reset and then do a idle relearn(or drive around town for an hour).
