I have replaced the o2 sencors and the code for them is still coming up and the van is using alot of fuel. When the gas guage gets down to a eight of a tank the guage goes crazy. One minute it will read empty and the next minute it reads full. Please help.

Sounds to me like you may have 2-different problems. With the gauge, I believe it is your sensor on the tank quantity float in your gas tank. The other problem may be another bad O2 sensor or a problem with the installation or wiring?
