What Are the Reasons for Frequent Stalling in Automatic Transmission Cars?
2 Answers
Automatic transmission cars frequently stall for the following reasons: 1. Engine carbon deposits. Automatic transmission models generally do not stall easily, while manual transmission models may stall due to driving skill issues. However, it is not impossible for automatic transmission cars to stall, and the reason is the use of low-quality fuel leading to engine carbon deposits and stalling. 2. Engine fuel system issues. For new cars, stalling problems are mainly caused by inexperienced driving skills, while another reason could be issues with the car's engine or fuel system. The likelihood of engine problems in new cars is very small, and most cases are related to the engine fuel system.
Recently, my automatic transmission car kept stalling, which made me quite anxious. There are several common causes: first, fuel system issues, such as low fuel pump pressure or a clogged fuel filter, preventing fuel from reaching the engine and causing it to stall; second, ignition system failures, like worn spark plugs or faulty ignition coils, making it hard to start and easy to stall; third, electronic control sensor malfunctions, such as a faulty throttle position sensor or oxygen sensor, sending wrong signals to the ECU and shutting off the engine; fourth, severe carbon buildup in the idle control valve, causing the engine to stop at low speeds or when parked; fifth, a faulty torque converter in the automatic transmission, affecting power delivery. I recommend first cleaning the throttle body and replacing the fuel filter. If that doesn’t work, take it to a professional shop to check for trouble codes. For safety, don’t delay.
