i was having trouble getting more than 20mpg in my 240.

the mechanic replaced:

airflow meter

O2 sensor

sonicblasted the injectors

replaced a leaking injector

and now i have a different 240 . . . .30mpg for mixed highway and suburban
driving . . . . and its got some power as well!!! wow :)

thanks guys for all your input over the last few weeks :)

and with the price of fuel these days, it was worth it :)
