bad gas miliage
#11
Lately I've only been getting 14 or 15 mpg, about a year ago I would get more like 17-18 (and I drive the same routes as I did then). I also have the hissing coming from the exhaust and the smell of gas. I'm thinking of changing the O2 sensor but could that be bad even without a check engine light coming on? I guess I'll also look at changing the plugs, wires, cat, etc.

It's hard to tell, but now that I think of it it does sound a little quieter than it did a few months ago. The thing is, I just got it smogged last month, so do you think I still could've passed even with a plugged cat? I'm in CA btw which, as we all know, is known for its **** emissions laws xD
