What are some common issues with the engine in my Vauxhall Mokka?

I have been experiencing some problems with my Vauxhall Mokka's engine and I'm not sure what could be causing it. Can you provide some possible causes and solutions for these issues?

One common issue with the Vauxhall Mokka's engine is a misfiring engine, which can be caused by faulty spark plugs or a clogged fuel filter. I recommend checking and replacing these parts if needed to improve engine performance. Also, make sure to regularly change your oil to keep the engine running smoothly.

Another issue that could be affecting your engine is a leaking vacuum hose. This can cause a decrease in power and efficiency. I suggest checking all of your vacuum hoses and replacing any that are showing signs of wear or leakage. This should help improve engine performance and prevent further issues.

If you're noticing a knocking sound coming from your engine, it could be a result of low oil pressure. I recommend checking your oil level and topping up if needed. It's also a good idea to have your oil pressure checked by a mechanic to make sure there aren't any underlying issues.

One more issue that could be causing problems with your Vauxhall Mokka's engine is a faulty oxygen sensor. This can lead to a decrease in fuel efficiency and engine performance. I suggest having your oxygen sensor replaced to improve your engine's performance and reduce emissions.
