ok I have noticed something.

does the fuel trim have to do anything with the MPG...??

say if I unplug the ecu the fuel trim values will be lost, will that affect the mileage, since the car will have to re learn the values..??

A long term fuel trim of more than about 5% indicates that there is an oxygen sensor problem or the calibration has not been tuned correctly.

What is the fuel trim, both long term and short term?
