Gas Mileage / O2 sensor
Hi All,
I recently purchased a 2005 Cobalt SS. I am afraid that this car may turn out to be a nightmare. It failed the inspection because the O2 sensors were burned out so I replaced both of them (the mechanic did) with bosch ones which I was told were very good. They are burned out again. Additionally, it looks like everytime I drive the car the gas economy is going down. It started at 24.7 and is down to 20.8. Any ideas what the possible causes could be? Thanks for any assistance

I am including a link to the US Department of Energy page - they have some tips on there on how to improve fuel economy. If I can be of any assistance, please let me know.
