This is a lean Code. What is happening is too much air is entering the engine and the O2 sensor is making the engine run rich to rebalance the fuel ratio.
You need to find the leak. Use a spray bottle of water while the engine is running. When you spray over the leak, the rpm will change or the engine may even stall. This is where repair is needed.
If you run with a check engine light on then you are looking for big dollars for repairs.. The light is there to tell you to have the fault codes read so that repairs can be kept to a minimum. So run the fault codes and find the fault .
Spark plugs in your car are good for 100,000 miles. try changing fuel filter and add a can of B&G 44K fuel additive. This stuff is the best on the market and only available at dealerships. It conditions fuel pump and injectors, also absorbs water in fuel (methanol). Try this first, your car is too new for any other problems. this should help drivability and fuel mileage. If Nissan does not have B&G, I know Toyota does. Also stay with 91 octane fuel. Check oil and coolant often. do not risk overheating in traffic, watch your gauges......
Sure sounds like a typical case of dirty/contaminated fuel....or a broken vacumn supply hose around the intake manifold area, in neutral let it idl;e and look and listen for a hissing sound, or a broken black rubber hose.
Also have the computer scanned for any possible codes.
Another thing to look at is the catalyctic converter, put a vac. gauge on the engine and see if the vac drops to almost zero...indicating a plugged cat.
fuel filter couldn't be removed huh !!! hmmm i think there would be no better place to start with than the fuel filter then onto the air filter etc ..but replace the fuel filter for sure
