Update:
It's been mighty cold. -17f last night.
I have not yet disconnected the MAF sensor, but plan to do that in the morning during some driving around. It's been a busy, busy week. What I have found, though, is that if as soon as I start it, I crank the heat and fan all the way up, it drives smooth the entire trip. If it hasn't, however, had sufficient cold soak time, it does do some sputtering until I drive it far enough to freeze it back down.
New Development: Hit a pothole on the way to the office the other day. ABS and Traction lights illuminated, and stayed on. As soon as I parked, I restarted the car, and they went off. Since then, at some random point in my drive, they both come on. Usually when I hit a bump. Coming into my neighborhood tonight, I slammed the brakes just to see, and it didn't seem like the ABS was working.
If it ain't one thing, it's another
