O2 sensor??? 850

posted by  someone claiming to be canadian on  Mon Feb 24 11:45 CST 2003 [RELATED]

i had posted earlier stating that i have been experiencing poor fuel economy (390km per tank) in my 95 850T. i am still getting this horrendous milage out of the car for the last month and a half and am curious if it could be the O2 sensor.

The car is well taken care of, tune up in the summer. air filter is good, tire pressure is up. i am getting no codes from the car, and it does not smell rich. (except when i realy step on it)

No check engine lights, could it be the MAF sensor? or an O2 sensor? are there any checks that can be done??

Any ideas??

Thank you

    canadian:

    390km/72liters is pretty low. i would say you have a leak somewhere in the system, i.e., the fueltank, fuel lines or near the fuel filter. leaks in fuel line are more pronounced when fuel pump is working, i.e., line is under pressure. i remember a leak i had on the short rubber hose input to the fuelfilter of my previous volvo, a 740gle, which was visible only when the engine was running.

    not to alarm you here but you need to you rule out if you have a leak before you drive that car anymore.
