Do you know the reason for car stalling while accelerating? why does your car stall when you accelerate? The most common reasons are moisture in the distributor cap, a vacuum leak, or a bad throttle position sensor, but whatever the reason is, it all depends on the conditions when the car stalls when accelerating happens, like if the car stalling happens on cold rainy mornings, if the car stalling is gradually becomes frequent, if the car stalling happens at any engine temperature. Different conditions have different causes of why car stalls while accelerating.

Car stalling while accelerating happens during cold rainy mornings
If the car stalling while accelerating happens during cold rainy mornings, it means that the cause of stalling is the moisture on the distributor cap. During the night when the car is parked outside the garage especially when raining condensation is formed inside the distributor cap. The moisture that forms will allow electrical current inside the distributor cap this current will lead to misfiring. It eventually becomes severe to the point that the car will stall while accelerating.
How will you avoid this problem?
If you anticipate that it is about to rain, park the car inside covered parking and leave it there overnight. In this case, no condensation will be formed inside the distributor cap.
Car stalling gradually becomes frequent
If car stalling while accelerating has gradually become frequent such as after the first time it took too long to happen again then the possible reason is that the car suffers from a vacuum leak. The problem of vacuum leak usually starts out small then gradually become worst, this is because of the pressure build-up inside the engine. The vacuum that is created inside the fuel system is one of the factors that determines how much fuel the car can get.
Now, if there is a vacuum leak on the fuel system the air/fuel mixture that enters the combustion chambers will be affected thus resulted in engine stalling. Bring the car to a reputable repair shop, ask the mechanic to check the engine for a vacuum leak. Usually, the EGR and the PCV valve is the most common source of a vacuum leak.
Car stalling suddenly happens at any given temperature
If the car is stalling while accelerating at any given temperature happens, the possible problem is a bad throttle position. Engine with fuel injected system has a part called throttle position sensor, the purpose of the device is to measure how far the driver pressed the gas pedal and thus the throttle. All gathered data will then feed to the engine computer that does the calculation, based on the calculation the resulting data will be used to determine how much gas the fuel injection system should inject to the engine combustion chamber.

Now, if the throttle position sensor provides the wrong data to the engine computer it will adversely affect the injection of gas that goes into the engine and it will result in car stalling while accelerating. Bring the car to the repair shop, ask the mechanic to check the throttle position sensor, have it repaired if necessary this will fix the problem.Related Articles:
