Back-fires are caused when unexploded fuel hits the hot tail-pipe. You have a problem with a spark plug not firing or the timing of the spark is off. This is most likely caused by a faulty distributor cap or a faulty spark plug. You may also have dirt inside your engine which is causing the spark plug not to work.
Every while, a car needs a tune up. A tune up will stop this from happening.

MAF sensor is telling the fuel system that the engine needs more fuel. You have dry-rotted vaccum lines and a bad MAF sensor. It will cost a hundred or two bucks to fix but it will fix it. Good luck....It is fuel injected right?
