What causes engine shaking in older Jaguar 6-cylinder engines?
1 Answers
Older Jaguar 6-cylinder engines may experience shaking due to the following reasons: 1. Excessive engine carbon buildup: After a certain mileage and duration of vehicle use, some carbon buildup is inevitable. Excessive carbon deposits can easily cause engine detonation and shaking, adversely affecting engine power output, significantly increasing fuel consumption, and polluting the environment. 2. Unstable oil pressure: Typically, abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can cause body shaking. In such cases, it is necessary to conduct a comprehensive inspection of the vehicle's fuel supply system at a certified service station to determine if there are any leaks and identify the cause of the shaking. 3. Abnormal ignition system: This situation may be caused by severe spark plug carbon buildup, low ignition voltage, or poor spark plug ignition performance, which are also major reasons for vehicle idle shaking.
