[Really bad fuel economy]

Hello all who have greater knowledge than me on the subject of Suby.

I have a 95 standard legacy wagon, EJ22 engine, Im getting really bad fuel economy and not from driving it hard, general cruising gets me maybe 350km on a full tank.

Extra story bits, i have a CEL on which is the fun p0325 Knock sensor code,

The car sat for a year before i got it, could the injectors be dead or dieing?

 

I have replaced oil and fuel filters, engine oil and tranny fluid, new plugs

 

Any ideas to increase economy would be greatly appreciated

I dont want to if i dont have to

[I finally made it]

Hi all, signed up a few days ago after buying a 95 Lego base , Manual wagon with 257,000 km on her,

Runs pretty good but has a CEL on, with a P0325 code for Knock sensor circuit, Sensor looks fine, no cracks and is torqued properly and in the correct position.

Took it for a rip on some windy roads the other night giving it a good boot full to see what she had and after that the CEL turned off until about halfway home when driving at abour 60km in 3rd the Cel came on again. Is that normal behavior for a Knock sensor and do i just get a new Sensor?

Also im only getting maybe 350km to a full tank of gas, "normal" driving, im thinking this is way low and am interested in any ideas how to clean this old girl out a bit.

Would a fuel filter help that much? Any other ideas on what to check and clean out?

Thanks in advance
