How to diagnose engine trouble in Vauxhall Vivaro?

I have been having some trouble with my Vauxhall Vivaro's engine lately. It's been making strange noises and there are occasional moments of loss of power. How can I diagnose the issue and get it fixed?

First of all, you should check the engine oil level and make sure it's not too low. Low oil can cause engine problems. Also, check the spark plugs and replace them if they're worn out. You could also try cleaning the air filter. If the issue persists, it's best to take your vehicle to a trusted mechanic for a thorough diagnosis and repair.

I had a similar issue with my Vauxhall Vivaro and it turned out to be a faulty fuel injector. I had to replace it and the issue was resolved. It's important to take your vehicle to a professional for proper diagnosis and repair, trying to fix it yourself could lead to more trouble.

Have you checked the exhaust system? Sometimes clogs or leaks in the exhaust can cause engine problems. If everything else seems fine, it's worth taking a look at the exhaust system. If you're not experienced in this area, it's best to seek professional help.
