Will bad spark plugs make engine shake?

Yes, bad spark plugs can cause the engine to shake. Spark plugs are responsible for igniting the air-fuel mixture in the cylinders of the engine. If they are not working properly, the mixture will not ignite properly and the engine will shake.

Here are some of the signs that your spark plugs may be bad:

* Engine shaking or misfiring

* Reduced fuel efficiency

* Difficulty starting the engine

* Stalling

* Check engine light illuminated

If you experience any of these symptoms, it is important to have your spark plugs checked by a qualified mechanic.
