Im diagnosing a rough idle and worst than normal mpg in my RRC, so I'm pricing out o2sensors and seems to be a huge price difference. Can someone guide me

Not quite as cheap as the splice in type, but a few bucks cheaper than the OE rover type from AB..

The NTK 25016 is a direct replacement for the stock sensor. 81 bucks at amazon : http://www.amazon.com/NGK-25016-Oxyg...=5336118855-20

Rough idle/bad mpg is probably not the O2 sensors. Look for vacuum leaks like cracked hoses, open vacuum ports and stuff. Main culprit are the vacuum lines for the cruise control. Second is the lines for the charcoal canister. It may be a zero-buck fix.
