i have a strong gas smell in my Infiniti when driving, also im having an acceleration problem when pressing my foot on the gas every now and then when driving, it also hesitates when that happens making me have to pull over and turn the car off for a minute then turn it back on and rev it at the same time. I was think that it might have to do with the fuel injector but im not sure.

Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.
