What Causes an Automatic Transmission Car to Stall at Low Speeds?
2 Answers
Reasons for an automatic transmission car stalling at low speeds: 1. The engine is out of fuel; 2. Water has entered the engine; 3. The use of poor-quality fuel leads to carbon buildup in the engine, causing it to stall; 4. For new cars, stalling is mainly due to insufficient driving skills. Another possibility is issues with the car's engine or fuel system. However, for new cars, the likelihood of engine problems is relatively low, with most cases being related to fuel system issues. How to handle stalling in an automatic transmission car at low speeds: First, turn on the hazard lights immediately upon noticing the problem to alert other drivers. Then, apply the brakes to bring the car to a stop as quickly as possible. After that, turn the key to restart the engine.
As an ordinary driver, I often encounter the issue of stalling at low speeds with an automatic transmission. There are several common causes. First, the throttle body gets clogged with oil deposits, blocking the air intake, causing the engine to stall, especially when stopping at traffic lights. Second, the spark plugs may be worn out or have carbon buildup, leading to poor ignition and insufficient power at low speeds. Third, the fuel injectors might be clogged or the fuel pump may not be performing well, resulting in unstable air-fuel mixture. Additionally, a faulty mass airflow sensor can send incorrect data, misleading the computer control. I believe regular maintenance is crucial. If you do it yourself, you can periodically clean the throttle body and check the spark plugs, inspecting them every six months or 10,000 kilometers. This reduces problems and makes driving more reliable and fuel-efficient. If the car stalls, don’t push it—pull over immediately and check or visit a repair shop to prevent minor issues from turning into major troubles.
