How to fix malfunctioning engine in Vauxhall Vivaro?

My Vauxhall Vivaro is experiencing issues with the engine. The engine makes strange noises and the acceleration is not as smooth as usual. Any advice on how to fix this issue?

Firstly, it's important to check the engine oil level and make sure it's at the recommended level. Low oil can cause strange noises in the engine. If that doesn't help, it's best to take it to a mechanic for further diagnosis.

Another possible cause for the engine issues could be a faulty spark plug. It's recommended to check and replace the spark plugs if needed. If the issue still persists, it's best to consult a professional mechanic.

I had a similar issue with my Vauxhall Vivaro before and it turned out to be a problem with the fuel injectors. I would advise getting them checked and cleaned by a mechanic. It could also improve the overall performance of the vehicle.
