alright guys, thanks for all advice. NAPA told me that the O2 sensor, or any sensor for that matter would flash a code. All I have is P0463 or something, it means the voltage to the fuel sending unit is too high and my fuel gauge has been inconsistent for about 4 years. I dont think this is related to fuel economy because i havent noticed any problems untill i made this post.

They recomended a fuel cleaner called B&K 400 (25$ !). I think it is helping, last time i checked i am up to 10.5 mpg, still not where i want to be. I have not replaced sensors and i am still trouble shooting. I may replace the O2's but it would be about 100 bucks to do so, just want to make sure that is the problem before i waste money on not fixing the problem. Thanks, all advice is welcome! Keep you all informed as this progresses....
