How do I fix a faulty engine in my Vauxhall Astra?

My Vauxhall Astra's engine has been malfunctioning lately and I'm not sure how to fix it. The car often makes strange noises and I'm worried it might break down on me. What steps can I take to address this issue and ensure my car's engine is functioning properly?

First, make sure to check your car's oil levels regularly. Low oil levels can cause engine problems and should be topped up if necessary. If the issue persists, it may be a more serious problem and you should take your car to a mechanic for a thorough inspection.

Another thing to consider is the air filter. If it's clogged or dirty, it can affect the engine's performance. Make sure to replace it regularly and keep it clean to avoid any issues.

It's also a good idea to check the spark plugs. Over time, they can become worn or dirty and can cause problems with the engine. If they are worn, it's best to replace them to ensure your car is running smoothly.
