When your car stalls, it can be frustrating enough to cause you to consider getting rid of it together. However, in most cases, stalling can be fixed and often avoided with proper maintenance and regular care of your vehicle. Here are five reasons why your car’s engine might be stalling and some tips on stopping it from happening again.
Failing Fuel Pump
A failing fuel pump is one of the most common reasons for a car’s engine to stall. If your fuel pump is not working correctly, it can’t deliver the right amount of fuel to your engine, which can cause your engine to stall. Fuel pumps usually fail gradually, so if you’ve been having occasional problems with your car stalling, it’s worth getting your fuel pump checked out.
Dirty Air Filter
A dirty air filter can cause your car’s engine to stall because it’s not getting enough air. When the engine isn’t getting enough air, it can’t run properly and will stall. So you should have your mechanic check your air filter every few months and replace it if it’s dirty.
Old Spark Plugs
Another one of the most common reasons a car’s engine might stall is old spark plugs. Over time, spark plugs can become worn or damaged, which can cause all sorts of car trouble. So if your car’s engine has been stalling, it’s a good idea to have a professional check the spark plugs and see if they need to be replaced.
Throttle Body
A throttle body is a device located between the air filter and the intake manifold of an internal combustion engine. It controls the amount of air that flows into the engine based on how much fuel is burned. If your car’s throttle body is dirty, it can cause your engine to stall. Your mechanic should clean the throttle body periodically using carburetor cleaner spray with throttle body cleaner.
Vacuum Leak
A vacuum leak is a common reason a car’s engine might stall. For example, a leak in your intake manifold can cause your engine to run lean and eventually stall. Your mechanic must diagnose the problem and possibly replace the intake manifold.
A stalling engine can be a real pain, especially if you get stranded on the highway. Please don’t ignore this issue, as it won’t go away on its own, but it will worsen. Instead, see your trusted mechanic diagnose your car’s engine and get it back running as it should.
