Answer
Johann,

I would be looking to see if there are any codes.  From what you say you probably have a mass airflow sensor going out or a connection that is loose.  You really need a code reader to see what the computer is registering.  The low fuel economy is a dead give away that a sensor is out of specification.  The car will usually retard the timing and richen the mixture to protect the engine until the error is corrected.  If your local shop has a code reader you are in business.  If not you may purchase a generic OBDII reader on-line from many a different shop.  CHeck it out and email me back.
