[SanMariana]

You can replace the spark plugs or clean the throttle valve to solve the problem. Here are the relevant details: 1. Haval: Haval is a sub-brand of Great Wall Motors, established on March 29, 2013. The Haval brand, primarily focusing on SUV models, operates in parallel with the Great Wall brand, using an independent logo and having its own product development, production, and service systems, mainly engaged in SUV production and sales. It includes three series: H series, M series, and F series. 2. Spark Plugs: Spark plugs are critical components of the ignition system in gasoline engines. They introduce high voltage into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. They mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell.
