So, Elise died on me on my way to work this morning. In the middle of a turn. I wound up coasting into the ditch. Got her fired back up, and she ran rough and shifted hard the rest of the way in. Thankfully she threw a code, which I was able to use to determine that the mass air flow sensor was probably borked. Ordered a new one this morning from my HUB store, and got it around noon. Got it installed after a short lunch, and instant improvement all the way around. So for now, she seems good to go.
