Engine Performance problem
2000 Ford Taurus 6 cyl Front Wheel Drive Automatic 88000 miles
Hello everyone, I'm confident that there is a solution for my problem as opposed for me to settle on 12 MPG. So I purchased a ELM327 OBD scanner and used EasyOBD2 free software.
Also I disconnected my MAF sensor to see if I noticed any improvement (disconnected on obd reading) however haven't driven yet since disconnecting, but check engine light did come on after a test run which was expectable.
(Was told that I should disconnect MAF, or O2 sensors to see if I notice an improvement disconnecting a faulty sensor, which now honestly I suspect MAF or O2)
The car has been a gentle ride, engine sounds strong, transmission good, besides 2 really cold days that it gave me some trouble to starting and RPM's jumped around that day after it turned on I NEVER received a check engine light before I'm sure there is information here that can conclude a solution.
Here is a detailed summary for your fair opinion.
-Car was purchased from a friend who alway gave good maintenance. (88K Miles)
-Has always given me around 12-13 MPG since purchase. (Friend never bothered finding mpg's)
-Received a FULL tune up just 2 months ago with same results : (. [LIST OF PARTS]
Air filter, Fuel filter, Sparkplugs + wires, Hcv valve, Oil change. Tires filled to 32 PSI.
-I'm an economic driver. Try to keep the automatic on the highest gear without hard accelerating, never jackrabbit, overdrive ON always, anticipating stops. Etc.
-My 12MPG average is with 60% city 40% highway, usually getting a terrible 160-180 miles / 13 gallon fillup.
