Answer
Hello and thanks for the question...I'll try to help.
If the Engine is low on coolant and also skipping at the same time, I would say you're looking at a head gasket job. Also, disconnecting the battery won't do a thing, since the vehicle is a 2002, it is OBD II and stores the codes, no matter what.
I would loosen the radiator cap and start it, IF there is air bubbles in the radiator, you have a blown head gasket and it need to go to a shop.
Other then this, I really can't guide you much more, unless the vehicle is in front of me.
Hope this helps,
Erik
