SOURCE: Check Engine Light Comes on Intermittently
The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.
SOURCE: 03 honda Odyssey gas smell and check engine light
I've got a '99 Oddy with the same symptom of gas odor inside and outside of the vehicle. Gas cap was secure and the level of fuel made no difference, so by process of elimination, I checked and followed the fuel lines and made sure there were no cracks that I physically could put an eye and hand on and eventually ended up at the fuel injectors and fuel rail. From there, all you need to do is remove the plastic cover plate from the intake plenum and the injectors will be exposed as well as the fuel rail. Turn the car on and wrap some paper towel over your hand like a mitten and run it over the suspected areas. You'll either find your leak there or the fuel filter located under the rear sliding doors.

When a cylinder mis-fires there is a reason. The dealer should have told you that. Most likely you have a fouled out spark plug. Which means you need new spark plugs and maybe wires. All this would be covered in a standard tune up. Once the bad spark plug is replaced, the computer will quit registering a mis-fire. Please give good ratings, they meen a lot to us.... Thank you

SOURCE: gas light stays on even when tank is full
the float sensor attahced to your fuel pump sounds as though it is not working properly. Usually this occurs when the car rides on E many times and becomes damaged. depending on the model it may be necessary to replaced the sensor assembly or if it is the complete unit the whole fuel pump.
Also, depending on your driving habits your car can use more gas if your are driving in traffic (stop and go). Average out your fuel mileage by filling up a few times and keeping a log of the gas consumed. Do this by reseting the trip meter when you fill up and when you fill up again divide the total mileage on your trip meter by the amount of gas you used by getting the amount of gallons it took to fill up again. ex. 360miles divided by 10gals = 36 miles per gallon.
note. make sure you check your air filter (is it clean?) and tire pressure (32psi) these can be contributing factors to poor gas mileage
