Since I didn't get any replies on my question of getting my mpg back up to the 30+ mpg range I'll see if I can ask a related question that may answer my first one.
I've noticed that my 92 Taurus wagon has been running rich - I can smell unburnt fuel at idel and other times. I'm guessing that whatever is causing my engine to run rich is also what's causing my loss of miles per gallon.
I've read some about the many sensors and how they interact. I've changed the two O2 sensors on the exhaust manifold, gently cleaned the Mass Airflow Sensor, changed the cap and rotor, changed out the ignition coil and changed to a K&N air filter all with no effect.
Would it be worth the money spent to take my car to the dealer - does the dealer in fact have the best diagnostic machine - to see if any of the sensors show up as malfunctioning?
have the same problem?
