Probably the O2 sensor. Have you checked that yet?

try temp sensor......since it shows a big affects to the gas mileage....mine has a pretty bad gas mileage too....but i just hate to change it around .....

Maybe the amount of coolant is a big factor too....don't overtop the coolant....top it in a pretty good mixture of water and coolant.....

This is from my experiences

Please do a SEARCH. This topic is brought up relatively often and they same question and answers each time. Just trying to point you in the right direction. Thanks

make sure you're calculating mileage correctly - my car said empty, i filled her up, and it only said 12 gallons - so there's probably around 3-4 gallons in reserve.
