What are the common problems with the Vauxhall Vivaro's engine?

I have a Vauxhall Vivaro and I'm experiencing some issues with the engine. It's making strange noises and it feels like it's struggling to accelerate. What could be causing these problems and what can I do to fix them?

Based on your description, it sounds like your engine may be experiencing a misfire or a problem with the fuel injectors. This could be due to a clogged fuel filter or worn spark plugs. I would recommend getting your engine checked by a certified mechanic to properly diagnose and address the issue.

Another common issue with Vauxhall Vivaro engines is a faulty EGR valve. This can cause rough idling and decreased performance. If this is the case, the EGR valve will need to be replaced. It's best to have a professional mechanic handle this repair.

I had a similar issue with my Vauxhall Vivaro's engine and it turned out to be a problem with the mass air flow sensor. I would suggest checking this component to see if it needs to be cleaned or replaced.
