Update:
I had CarMax (where I bought the car) replace all the filters, change
oil, and install platinum spark plus. No change in mileage.
CarMax showed me the records where they had gone over the
car to the equivalent of a 90K checkup when they took it in
from previous owner.
I called the cor****ate office in the East, and they suggested
clogged fuel injection.
Went to my nabe mechanic with a note about the sensors that
was suggested here, as well as clogged fuel injection suggestion.
He went over everything, including putting in the scanner for codes.
He said everything was fine except the fuel injection, so he
"unclogged" all six, and also replaced (?) connection wire(s)
on one injector.
He said I should fill it up, take it out at freeway speeds for at
least 1/2 hour to an hour, then fill it up again and measure fuel
consumption. (This is unwittingly humorous, since freeways
around LA are all "clogged" at any hour of the day or evening -- go
find one that permits "freeway speeds"!)
So I will do that tomorrow and HOPE that the $505 (!!!)
I spent will up the mileage.
He also pointed out that my 99 GLE has a LARGE V6,
which I didn't realize. I know I won't get the mileage
I had with my late, lamented, totaled Toyota Corolla,
but I KNOW there has been a decrease since I bought
the Nissan, so wish me luck!
