John...

First thing you need to do is fill the tank..drive most of it, then fill back up and calculate your mileage. This will give you a true picture of MPG.

As for the things you know that need to be addressed. Yes, fix them. they might be contributors.

This sounds alot more like a mechanical problem than something that belongs in Performance and Brainstorming. I'll move it for you.

I think what you are saying is your getting a little over 10 mpg. Something is terribly wrong. Have you done a tune up recently? If so what have you done. How many miles are on the 02 sensor. You could take it out and look at the tip. If its charcoal black, replace it.

i gave the car full tune up about 5 months ago.. i rep;laced everything execpt the o2 sensor and the gas filter.... i will check out my o2 sensor tonight and get back with my reply........ thanks

Low tire pressure is something that a lot of people overlook, but it is such a cheap and easy fix that there is really no excuse for it. You can expect to get worse mileage when driving with the AC on, especially in town stop and go driving.
