Can Automatic Transmission Cars Stall?
2 Answers
Automatic transmission cars can stall. Here are the relevant explanations: 1. Throttle valve contamination: Carbon deposits on the throttle valve directly affect its operation. If not cleaned for a long time, carbon buildup can cause errors in the throttle opening and allow air with impurities to enter the engine cylinders, leading to abnormal engine operation. 2. Fuel injector clogging: The fuel injector in the fuel system is prone to carbon deposits. Over time, carbon and gum formed from gasoline combustion can adhere to the injector, causing carbon buildup and even clogging. 3. Fuel pump failure: A faulty fuel pump can result in insufficient fuel supply, with symptoms similar to other fuel system issues (like injector failure), such as weak acceleration, fuel cut-off during sudden acceleration, difficulty starting, abnormal noises, engine shaking, and in severe cases, stalling while driving—including automatic transmission models. 4. Ignition coil failure: If the ignition coil fails, it can cause abnormal engine operation, shaking, weak acceleration, and misfiring. Failure of multiple ignition coils can lead to stalling. 5. Spark plug failure: Similar to ignition coil failure, faulty spark plugs can cause misfiring, weak acceleration, and shaking, often referred to as "backfiring." Multiple spark plug failures can result in stalling while driving, including in automatic transmission cars.
I've been driving automatic transmission cars for almost ten years, and they rarely stall because the automatic transmission takes care of the clutch and gear shifting for us, unlike manual transmissions where you might accidentally stall. But after all, cars are machines, and there can always be unexpected situations, such as an old battery not supplying enough power, or spark plugs in the engine failing, making it easy to stall when starting. If there's a problem with the fuel system, like a broken fuel pump not supplying enough fuel, the car can also stall. My friend's car once suddenly stalled at a red light, scaring him into restarting it immediately. If you feel something is wrong while driving, like the engine shaking violently or the lights flickering strangely, it's best to pull over and check. Regular maintenance is crucial; changing spark plugs and the battery on time, along with maintaining the fuel system, can greatly reduce such problems.
