Make sure you're using the recommended spark plugs. When my car did that, I had put Bosch Platinum Plus-4 plugs in and got that same problem. Turns out the plugs are too hot and cause it to fire prematurely and kick the misfire code.

You may have damaged one of the sensors or tore the wire off. You will have to take it to someone with a, "high quality scanner" and have them get the code out of the computer on your car. Most $100 scanners won't pull the ABS codes out.

If you are still stuck in the driveway, that's why the ABS light is still on. Get a snow shovel and dig the car out. Once you get the car on the road and all the wheels are turning the same speed the ABS light will most likely go off. It doesn't hurt anything to drive the car with the ABS light on. What that light is telling you is, the "Antilock Brake System" (ABS) is not working. The brakes will still work but, the antilock portion will not, so when you hit a icy patch, the wheels can lock during braking. The ABS senses the speed of all the wheels and if you have been spinning the wheel in the snow, it throws the system out of sychronization. Once you get out of the snow and you start to drive the light will go off, if the system is in working order. The light should go off in a block or two, if not stop the car shut the engine off and restart it. Try it again and see if the goes off, if not there's a problem with the system, get it to a shop.

could be a burned valve. Run a compression test. If you need instructions or have more questions, please let me know.
