2.3L ('83-'97) Reconsidering awful MPG

[Brain75]

3 choices, same results... wouldn't spend the money on #4.... I need to go through all the posts again and read carefully - see if anything springs to mind.

did you clean any/all of those MAF sensor options?

The electrical issues could certainly cause issues with the computer and sensors, giving false readings. You might be in "limp home mode" more often than not. That will certainly affect mileage, as would faulty readings on any of the sensors. If you've cleaned the three MAF sensors and still get the same results no matter which you use I'd say they are probably all fine... or all bad...
