22mpg's in a 1997 Saab 900s

I have a 97 900s, autotragic...being auto dosen't bother me as much as the 22mpg it gets. I have notice the mpgs dropping by X% for two months. I have use a fuel system cleaner and drive it in a fashion that not even the girlfriend complains about.

But the milage is still dropping. Is dropping the fuel tank the only way to get to the fuel filter? what else could help out this "pump pig"?

O2 sensor.

my 94 900 SET only ever got me around 26mpg.. and that was a 5 speed.

Pretty sure the ethanol swap happens around here in October. Do they do that by you?

The fuel filter should be accessible from uner the car behind one of the door, drivers side if I remember correctly.

looks like the filter is on the passenger side, but i will be doing the o2 sensor and the spark plugs at the end of the week :)

thanks ,Dave
