What causes a car to shake while driving and stall, but restart normally?
1 Answers
It may be caused by circuit faults or sensor malfunctions, such as issues with the throttle position sensor or air flow sensor. Sudden stalling while driving generally has the following causes: 1. Ignition system: For example, weak spark plug ignition capability. 2. Short circuit in low-voltage lines causing stalling: In this case, the stalling is intermittent, and the low-voltage lines need to be checked. 3. Component failure: This issue is usually related to capacitors or electronic ignition modules. The car can start initially but stalls after a while, then can restart but stalls again. 4. Fuel supply: Remove the air filter and press the accelerator pedal. If gasoline sprays from the carburetor accelerator nozzle, the fuel system is working normally; otherwise, the fuel supply is abnormal. 5. Circuit fault: Pull out the central high-voltage wire and start the engine with the starter. If there is no spark from the central high-voltage wire, the ignition circuit system is faulty. 6. Carbon buildup: Cars driven frequently in urban areas are prone to carbon buildup in areas like the throttle. Occasionally driving at high speeds can help clean carbon deposits by flushing them at high RPMs, cleaning the fuel injectors, throttle, etc.
