Why Does My Car Stall Every Time I Put Gas In It? | Browning Kimball Classic Car Museum

Putting gas in your car is a routine task that you do without thinking. However, if your car stalls every time you fill up the tank, it can be frustrating and worrisome. There are several reasons why this might be happening, and in this article, we will explore some of the most common causes and solutions.

Dirty Fuel Filters

Fuel filters are designed to trap dirt, debris, and other contaminants from entering the engine. Over time, the filter can become clogged and restrict the flow of fuel to the engine. When this happens, your car may stall or have trouble starting. To fix the problem, you need to replace the dirty fuel filter with a new one.

Faulty Fuel Pump

The fuel pump is responsible for delivering fuel from the tank to the engine. If the fuel pump is faulty, it won't be able to provide enough pressure to keep the fuel flowing smoothly. This can cause your car to stall when you put gas in it. A professional mechanic can diagnose and replace a faulty fuel pump.

Vacuum Leaks

Your car's engine relies on a vacuum to operate certain components, such as the fuel system and transmission. If there is a vacuum leak, it can cause your car to stall when you put gas in it. A vacuum leak can be caused by a cracked or damaged hose or a malfunctioning valve. A mechanic can identify and fix the problem.

Dirty Throttle Body

The throttle body controls the amount of air that enters the engine. Over time, it can become dirty and clogged with debris, which can cause your car to stall. To fix this problem, you need to clean the throttle body with a special cleaner.

Bad Idle Air Control Valve

The idle air control valve regulates the amount of air that enters the engine when the car is idle. If it's faulty or dirty, it can cause your car to stall when you put gas in it. A mechanic can test the valve and replace it if necessary.

Loose Gas Cap

Believe it or not, a loose gas cap can cause your car to stall. The gas cap seals the fuel tank and keeps dirt and debris out of the fuel system. If it's loose or damaged, it can cause air to enter the fuel system, which can cause your car to stall. Make sure your gas cap is tight and in good condition.

Conclusion

If your car stalls every time you put gas in it, it's important to get it checked out by a professional mechanic. Ignoring the problem can lead to more serious issues down the road. By identifying and fixing the problem, you can ensure that your car runs smoothly and reliably.
