How to fix a malfunctioning engine in a Vauxhall Astra?

My Vauxhall Astra's engine is making strange noises and the check engine light is on. What could be the issue and how can I fix it? I am concerned that it may cause further damage if not addressed promptly.

It is important to pay attention to any strange noises coming from your engine as it could be a sign of a larger issue. In this case, it could be due to a faulty spark plug or a problem with the fuel injection system. It is best to take your car to a certified mechanic for a proper diagnosis and repair.

Make sure to check your car's manual for any specific maintenance instructions for your Vauxhall Astra's engine. It is also a good idea to keep up with regular oil changes and tune-ups to prevent any potential issues.

If you are on a tight budget, you can try replacing the spark plugs and fuel filter yourself. However, it is always recommended to seek professional help for any engine-related problems as it can be complex and may require specialized tools.
