loewent,
I do not think that fuel guage is to blame. Since MPG went back to
normal, the last tank lasted (until low fuel light went on) for 340
miles (as opposed to 180 miles when I screamed for help).
I am still puzzled why MPG suddenly dropped from 300+ miles per tank
to 180 miles per tank and then suddenly went back to normal. I am
reluctant to blame bad gas since I did fill up at the same gas station
before. In addition, such a poor gas quality must have resulted in
power loss, which I did not notice.
I think that tem****ary MPG drop might have been computer related. If I
am not mistaken, computer adjusts ignition timing based on gas quality
(octane number) so that there is no detonation. As I mentioned before,
I installed anti-theft device just before MPGs dropped. I had to
disconnect computer while I was installing anti-theft and that might
have reset computer memory, specifically its adjustments to gas
properties. Once I filled up the next tank, computer migt have
adjusted back and MPGs went from 180 miles per tank back to 340+ miles
per tank. I am not a specialist in car electronics. Does my
explanation seem realistic?
