A: All the codes you list indicate both a lean condition and a misfire. I think you may be on to something when you say the problem happens when the tank is less than half full and goes away when filled up. My thought process goes to a problem that Chrysler had many years ago with the fuel tank pickup tube. These tubes would develop a hole halfway up. When the tank dropped under a half, the fuel system would push air and fuel mix rather than the straight fuel mix. When the tank level was higher than the hole, it would push fuel only, although at a lower pressure. Sounds like an interesting job. It could get expensive, but diagnostics need to be done to be sure.
Car Care Tip: When preparing your emergency winter-driving kit for the trunk of your car, do not forget a blanket and a can of WD-40, along with your usual supplies. It is also a good idea to throw a pack or two of sealed peanut butter crackers in your glove compartment.
