Hi guys, my car gets pretty horrible gas mileage and has 106k on it. Everything is basically replaced on it from a tuneup except for the MAF (which I cleaned), the PCV valve, and the o2 sensors. I don't have a CEL on at all and $120 for autozone o2 sensors seems a little pricey just to throw parts at my car for something I'm not too sure of. Is there a better place to buy them at? or do you guys think I should maybee take a q-tip and some carb cleaner and clean my existing ones up a bit? Thanks for any help guys.
