What happens when a valve is stuck in the open position?

Why does my car stall?

These sensors monitor different parameters to keep the engine running at optimum performance. One of these sensors is the mass air flow sensor. This keeps track of the amount of air that enters the intake system and the combustion chamber. If there is a problem with this sensor, then it can send faulty signals to the car’s computer. The engine will also not produce the optimal power it used to. With sub-optimal power, the car will not be able to continue running when it is at low speeds. The same is true with a bad or dirty oxygen sensor. This sensor tells the computer if there is too much oxygen in the fuel air mixture or too little oxygen. This way, the computer will make the necessary adjustments in fuel delivery. If it gets the wrong information, the engine may not get the right air fuel mixture for proper combustion.
