Even though it probably still says I am a noob, I have actively followed this site for over 7 years.
Now that is out of the way.
I have a peculiar issue. My subaru is really really Japanese which is awesome but there are some quarky things that one must deal with to drive this car.
About 2 months ago my fuel warning light on the dash went out and never came back on. At the same time that problem occurred,my fuel economy dove from 27-28 to 22.
Even more recently, I have a brand new battery, it is - 7° out and the car wouldn't start but was fine the rest of the day starting. I am suspecting a ground issue there but wondering more so if these issues are in some way related and if anyone has any suggestions. I have done the obvious. Looked for loose connections. Checked the battery and alternator which came out great.
Not sure about the dash light and fuel economy though.
