When your car stalls while driving but starts back, there are several possible causes. Your car may be having problems with its fuel tank or ignition system, mass-air flow sensor, or catalytic conversion. Don't panic. Most of these problems can easily be fixed by replacing just a few parts. Keep reading to learn how to diagnose and fix this problem, which is extremely frustrating.
Problems with catalytic converter
If your car stalls while driving but starts back after a few seconds, it may be time to have your car's catalytic converter checked out. Catalytic converters are designed to eliminate the emissions from a car's exhaust, and when they malfunction, they can cause a variety of problems in the engine. Here are some indicators to watch out for.
Poor compression. The mixture of fuel and air may be too sweet if the catalytic converter becomes blocked. The car may jerk as a result. Use a catalytic cleaner to clean your catalytic engine. While the mechanic may recommend one of these products to you, they can also be very costly. For proper diagnosis and repair, it is best to bring your car to a mechanic.
Fuel pump problems
A faulty fuel-pump is one of most common problems for cars. There are many reasons this can happen, including worn fuel pumps and faulty ignition. If your car stalls while driving but starts back up, you should check the fuel pump. You can prolong the life expectancy of your fuel pump by changing your fuel filter frequently to avoid fuel pump clogging. You may need to replace the fuel filter if your car suddenly stops driving, but it starts again.
In addition to malfunctioning ignition, the fuel pump can also fail to send the correct amount of fuel to the engine. When you turn the ignition, the fuel pump relay supplies fuel to the engine. This can cause whining and buzzing sounds. Sometimes, the relay is not delivering the correct amount fuel. In this case, your car may stop at highway speeds but resume normal operation after restarting. The warning signs that your car is unable to start due to a malfunctioning fuel pump relay will be obvious. It could be something else if your car stops while you are driving, but then starts up again shortly afterwards.
Problems with the ignition system
Car stalling can be a frustrating problem. Many reasons can cause car stalling. It is most likely caused by a defective ignition module. Either the ignition module is defective or the engine can be stopped. A bad mass air flow sensor could detect excess or insufficient air and shut down the engine. You may experience intermittent problems or a combination of both.
A faulty fuel filter or fuel pump can also lead to your car stalling. Fuel filter blockage can also cause stalling. A carb cleaner can be used to clean it if it's blocked. A new carburetor may be required if it is not. These solutions might not be enough to fix the problem. Your mechanic might suggest that you inspect the engine control module and crankshaft position sensor if you aren't sure what is wrong.
Problems with mass air flow sensor
Problems with the mass flow sensor could cause your car to stall while you are driving, but it will start right back up. This is a sign that the mass air flow sensor has not been reading accurately. Try driving the car with the sensor off to verify. The computer will estimate the airflow and might even give better results. Depending on your car, the computer might give you a more fuel mixture than what the car actually uses.
If you experience any of these symptoms it is likely that your car’s mass air flow sensors are defective. This sensor monitors the flow of air into and out the combustion chamber. If the sensor is not working correctly, your car may not get the correct air-fuel mixture. Your engine could run lean and rich. You should immediately get your car checked for this problem.

How To
How to correctly diagnose your vehicle for repairs
Before you can determine if your car requires repairs, it's important to first analyze the symptoms. These steps will help you diagnose your car properly.
-
Check engine lights. Inspect the dashboard light indicators. These include the engine lights, the oil pressure gauge and the battery light indicators. The RPM gauge and coolant temperature gauge should also be checked. If they have been flashing for more days than usual, it could be a sign that something is wrong with the vehicle.
-
Take a look at the treads. Tires that are worn can cause issues with handling and braking. The treads of the wheels should be inspected as well. They should be smooth and clean. It is best to take off the wheels and remove them. To check the condition of your treads, use a flashlight.
-
Monitor the level and consistency of your brake fluid. It is important to keep track of how much brake fluid you have in your car. This will ensure that your brakes run smoothly. If your brake fluid level is low they might not work properly when you apply pressure.
-
The suspension system should be tested. The suspension system in vehicles absorbs vibrations and shocks. This suspension system provides greater control and smoother acceleration and deceleration. Your vehicle might feel wobbly, or shake uncontrollably if it has a bad suspension. If you are unsure if your vehicle is suffering from a suspension problem, put weight on the front and rear axles to check the movement.
-
Examine the steering wheel. The steering column is used to link the steering wheel with the rest of vehicle's components. Accidents often damage steering columns. You should replace the steering column if it is loose or weak.
-
Observe the exhaust pipes. Exhaust pipes move gases from combustion chamber to atmosphere. You can let harmful fumes into your home if your exhaust pipes crack or leak. If your tailpipe bends, it is important to fix it immediately.
