Car Engine is Shaking
Causes
- Misfiring engine
- Vacuum leak
- Loose or broken motor mounts
- Unbalanced tires
- Damaged CV joint
- Transmission problems
Diagnosis
To diagnose the cause of a shaking engine, you will need to perform a few simple tests. First, check the engine for misfires. This can be done by removing the spark plugs and inspecting them for signs of wear or damage. If the spark plugs are fouled, they will need to be replaced. Next, check the vacuum hoses for leaks. A vacuum leak can cause the engine to run lean, which can lead to shaking. To check for leaks, simply spray a can of carburetor cleaner around the hoses while the engine is running. If the engine speed changes, then there is a leak. Finally, check the motor mounts for looseness or damage. The motor mounts are responsible for holding the engine in place, and if they are loose or broken, the engine can shake.
Repair
The repair for a shaking engine will depend on the cause of the problem. If the engine is misfiring, the spark plugs will need to be replaced. If there is a vacuum leak, the hoses will need to be repaired or replaced. If the motor mounts are loose or broken, they will need to be tightened or replaced. In some cases, the transmission may need to be repaired or replaced.
Prevention
There are a few things you can do to prevent your car engine from shaking. First, keep up with regular maintenance, including oil changes and spark plug replacements. Second, avoid driving on rough roads, as this can put stress on the engine and its components. Finally, if you notice any signs of a shaking engine, such as a rough idle or loss of power, have it checked out by a mechanic as soon as possible.
