A dead or malfunctioning oxygen sensor can mess with your mpg. Your car could be running in open loop mode meaning no computer control.
Next, extra weight removal,
Battery holding a charge? A dying battery can cost big time. If you run short trips with a lot of alternator load, your battery may be constantly charging sucking amps. Trickle charge overnight. Turn off electrical loads.
A block heater can help a lot on short trips even in California getting you up to operating temp much faster.
Rear wheel skirts are relatively easy and effective mpg help.
Lower your idle speed. Some times a lazy mechanic will set it by ear to save looking for the stock rpm. If you sit in traffic a lot and put your car in neutral or turn it off when stopped.
Check ignition timing. If it's retarded can cost mpg
Just some stuff I didn't see posted yet that worked for my van.
Keep trying, you will get there!

Actually I checked the tire pressure in my wheels this afternoon. The max is 35 and they are all at 37/38. I would go higher and I want to, but I need tires really bad so I don't want to risk losing any traction because the tread is almost gone.
There is definitely something wrong like the O2 sensor or something. I got all that stuff done to my car to get it into better condition... since then it has been really rough when first started. It starts but jumps between 250-1000 rpms and sounds like a clogged lawn mower trying to run on choke.
That stopped after about 2 days, and yesterday the Check Engine light came on... :'( I'm stopping at AZ to have the codes read tomorrow afternoon. Hopefully it isn't something expensive.
Rear wheel skirts are the next mod on the list if I can't find a beater bumper put an air dam on. Also, how do I change the idle speed?

Filling this aerodynamic gap at the base of external mirrors seams a great idea to me because it generates less perturbation at the front of the car so less drag at the rear (but my aerodynamic skills are limited to what I read here).

This one doesn't give as good of a view as my stock mirror, but I could navigate traffic easily with just the blind spot mirrors i have on the A-pillars. This mirror was just to make my car legal because you need an exterior drivers mirror in MI. It also works for if I have stuff loaded in the trunk and can't see out the back window, I can lean over and see behind me with this bullet-shaped mirror.
As for aero, it definitely helps a ton!!! The first day after I put the mirror on, (before the coroplast panel) The ride was really loud, and I could feel the car trying to drag through the resistance created by the hole in my door.
