O2 sensor Q's

Just wondering how well does replacing this sensor help my gas mileage?? Apparently im running rich… The smell of gas coming out of my exhaust is strong enough to burn my eyes!!

Well im currently getting 400k a tank. not too sure if thats good or bad. I’d done my oilchange, change spark plugs and wires, and seafoamed tank and brake vacuum line. I didn’t do the crankcase, didn’t want to oilchange again:(

So, any advice on where, what type(if there is more than one) of 02 sensor should I get? how much am I looking at spending? On top of that what else can I do to help my fuel issue. better intake system is next i guess…

p.s dont mind the noob post. THANKS!
