  • What will kill fuel economy??

    My fuel economy sucks as of late--I'm only getting like 16-18 mpg and it's really annoying, especially since the car performs so well--no hesitation, misfiring, etc. I've got a 2000 3.8--I have noticed a strong exhaust smell occasionally, especially after starting up in the morning--no major modifications to the car. Could it be one or both of my o2 sensors in front of my cat have taken a dump? My car has about 52k on it. OPEC sucks. Please help!!
