Why is my Vauxhall Zafira Life experiencing abnormal engine vibrations?

I have noticed that my Vauxhall Zafira Life has been vibrating more than usual lately. It seems to happen mainly when I am idling at a stoplight. What could be causing this issue?

Based on your description, it sounds like your engine mounts may be worn out. This can cause increased engine vibrations, especially at idle. I would recommend bringing your vehicle to a certified mechanic for an inspection and potentially replacing the engine mounts.

Another potential cause could be an issue with your spark plugs. If they are worn or dirty, it can affect the smoothness of your engine's idle. I would suggest getting them checked and replaced if necessary.

Have you recently changed your tires? Uneven tire wear can also cause vibrations. Make sure to have your tires rotated and balanced regularly.

It could also be related to your fuel system. A clogged fuel filter or dirty fuel injectors can affect the engine's performance. Try using a fuel injector cleaner to see if that helps.
