what causes my car to shut off while driving and smells burnt
Quick Answer. CarsDirect identifies three of the most common problems that cause a car to switch off while a person is driving: broken or worn vacuum hoses, faults in the fuel intake system or an electrical wiring problem.
A vehicle's fuel intake system pumps fuel into the engine. If it gets clogged or starts to leak, an insufficient amount of fuel can cause the engine to shut off without warning. Finally, the vehicle's electrical system provides the spark necessary to ignite the fuel and power the car's engine.
