What makes a car engine shake?


Answer by  scrtwrldfalxmac (107)

A shaking engine can be caused by worn engine mounts. As the rubber wears down on your mounts, it gives the engine more room to wobble which will cause the mounts to wear out even quicker. Another cause could be an unbalanced crank shaft. If this is the case, the crank shaft will need to be removed and tested.

this is what makes your car engine shake. you have a combustion engine, if you have a bad plug your engine could shake because its not running right so it will run hard not smooth like it should

Typically that is a sign off a misfire or detonation. This can be caused by poor quality fuel or incorrect engine timing. You should do a simply tune up on the engine checking your timing and plugs. Then fill it up with some fresh gas with the correct octane rating.
