Hi Guys, this is my first post so I hope I have put it in the right sopt. I am the proud new owner of a 2001 Pathfinder LE. its in good shape runs well... BUT. the Gas mileage is less then I thought. about 300KM I was hopoing for 400-450KM to a tank of 91 Octane. I have some engine codes. P0160 Oxygen Sensor Circuit No Activity Detected (Bank 2 Sensor 2) - see our "articles" link for additional help with these generic check engine light codes P0455 Evaporative Emission Control System Leak Detected (gross leak) P0140 Oxygen Sensor Circuit No Activity Detected (Bank 1 Sensor 2) - see our "articles" link for additional help with these generic check engine light codes P1448 EVAP Canister Vent Control Valve Open it runs and drive fine but if I push it, floor it it feel like its not quite getting all the power it should. what i want to know is if I replace the 2 O2 sensors could this well with the poor fuel mileage and lack of power? Thank hope I can get some info
