What Causes an Automatic Transmission Car to Stall Automatically?
1 Answers
Reasons for an automatic transmission car stalling automatically: 1. The use of low-quality fuel leading to engine carbon buildup and stalling; 2. For new cars, it may be due to insufficient driving skills, or 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. The normal engine speed for an automatic transmission is generally between 700 to 800 RPM. If it's too low, the engine tends to shake, and if it's too high, fuel consumption increases. Situations where the idle speed automatically increases by 50 to 150 RPM include: 1. Cold starts and low water temperature; 2. Battery depletion; 3. Turning on the air conditioning for cooling.
