What Causes the Buick Excelle to Shake a Few Times and Stall Automatically?

[RachelDella]

It may be caused by a camshaft solenoid valve issue leading to engine stalling. It is recommended to disconnect both the intake and exhaust camshaft solenoid valves and try starting the engine again. If it still fails to start, it should be handed over to a 4S shop for inspection and repair. Below is an analysis of the reasons for car stalling: 1. Electrical component failure: This problem is usually related to the ignition coil, capacitor, or electronic ignition module. The car may start initially, stall after a while, start again, and then stall once more. 2. Fuel system failure: This includes a damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or an empty fuel tank. In such cases, the car may still start, but with great difficulty. 3. Sensor failure: Faults in sensors such as the throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, or camshaft position sensor can also cause stalling issues.
