P2A00 & P0300 Misfire

Jordo!

You have a bad MAP sensor and that is probably causing intermittent misreads and incorrect fueling, resulting in a random lean miss and thus the P0300 code. The O2's do not appear to be related here, and seem to be working fine.

In short, yeahhhh... you should be fine at low to moderate load (i.e., normal driving) I wouldn't push it to redline until you get the MAP sensor replaced, as it's not clear how lean you are running when you miss (presumably not enough to be out of range on the fuel trims, but, still best to solve the problem before pushing it).

There was just a thread on this with details where it's located etc in the intake manifold, but if you are still under the drivetrain warranty, I would just take it to the dealer.
