Lincoln LS car shaking and not moving despite pressing gas pedal on Lincoln LS

Some Lincoln LS owners report experiencing shaking and a lack of movement despite pressing the gas pedal, which can be attributed to several potential issues. Misfiring cylinders are commonly cited as a cause of this shaking when the vehicle is stationary. Additionally, bad motor mounts may contribute to engine vibrations, particularly at idle. Engine damage is another serious concern that can result in poor performance and shaking. In colder conditions, extreme engine shaking and difficulty moving may be linked to low brake pressure or other mechanical problems. Some owners also notice vibrations at specific speeds, such as 41 mph or when reaching 50 mph, which could indicate issues with the carrier bearing or driveshaft. Furthermore, a hard brake pedal may suggest a significant air vacuum leak, potentially leading to misfires due to a lean fuel mixture. It is recommended that owners experiencing these symptoms have their Lincoln LS inspected by a qualified mechanic to prevent further damage and ensure safety.
