[DianaFitz]

Engine vibration at idle when the air conditioning is turned on may be due to issues with the ignition system. Here is some relevant information: 1. Origin: The first-generation Mondeo was produced between 1993 and 1996, named "Mondeo." This name highlights Ford's high hopes for the model. "Mondeo" is derived from the French word "Monde," originally meaning "high society," symbolizing classic and noble qualities. At the same time, "Mondeo" also carries the meaning of "Mondial," which translates to "worldwide." 2. Development: Since 1993, the Mondeo has been sold in Europe in hatchback, sedan, and station wagon versions. Total sales in the region have reached approximately 5 million units.
