Since my last post I had a chance to put a few tanks of gas through the car (after replacing plugs, wires, and O2 sensor), and I have noticed a consistent increase in fuel economy, I'm not getting about 330 to 340 out of a tank before I fill up (12 gallons to fill up so I'm getting about 27 to 28 mpg now), the fuel light is not on at that point yet. So replacing those parts did help noticeably, but I will also need to replace the valve cover seals yet.
