The computer may then not provide the engine with the correct amount of air while accelerating, causing a hesitation sensation.Дirty/failing fuel injectors: Fuel injectors spray fuel in a fine mist into the cylinder where it is mixed with air and ignited by a spark plug. If the throttle position sensor is not working properly, it may be sending incorrect information to the vehicleвЂ™s computer. The computer is then able to adjust the fuel/air mixture going to the engine so that is stays at an appropriate level. Throttle position sensor: A throttle position sensor tells the vehicleвЂ™s computer how far the throttle is open and how hard the accelerator is being pressed. A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. If a fuel pump cannot provide the correct pressure, fuel may have difficulty making it to the engine.

A vehicle with a failing mass airflow sensor may also stall soon after starting.ДЇuel Pump: The fuel pump in most modern vehicles sits inside the fuel tank and pumps fuel up to the engine.

When a mass airflow sensor begins to fail, it will typically generate an error code or вЂњCheck Engine light.вЂќ This warning may be accompanied by hesitation while accelerating, or while driving up a hill.

Mass Airflow Sensor: The mass airflow sensor measures how much air is entering the engine and relays this information to the vehicleвЂ™s computer so that the right amount of fuel can be delivered from the fuel injectors. Service type Engine hesitates during acceleration Inspection
