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 :)
