[JulianaFitz]

Check if the spark plugs have excessive carbon buildup and replace them if necessary. Below is relevant information: 1. If you have already cleaned the engine carbon deposits, cleaned the throttle body, replaced the oil pads and spark plugs, but still notice body vibration at idle, it is recommended to visit a 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal. 2. The Buick Excelle is another masterpiece launched by the Buick brand after the new Regal, new LaCrosse, and Enclave, based on the "global platform, European and American technology." It integrates the best dynamic genes that the Buick brand has endowed to mid-size cars, bringing a new five-door coupe driving experience to the mid-size car market. The launch of the Buick Excelle fills the product gap between the new Excelle and the new Regal for the Buick brand, and further strengthens and perfects the product lineup of the Buick brand.
