An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed. Several components of the fuel or air intake system could cause this jerking or surging sensation to happen. Issues within these systems can also cause fuel economy to worsen.
A common cause is a problem with the spark plugs or ignition system. Other potential causes include a blockage in the fuel line, a faulty oxygen sensor, or a problem with the mass air flow sensor.
