How to troubleshoot a malfunctioning engine in a Vauxhall Astra?

I have been experiencing issues with my Vauxhall Astra's engine and it keeps stalling while driving. What could be the possible causes for this and how can I diagnose and fix the problem?

Check for any clogged air filters or faulty spark plugs. These are common culprits for engine stalls in Vauxhall Astra cars.

It could also be a problem with the fuel system, such as a clogged fuel injector or fuel pump failure. Have a mechanic check these components to determine the root cause.

Another possible issue could be a faulty sensor or wiring in the engine control unit. A diagnostic scan can help pinpoint the exact issue and guide you in the right direction for repairs.

In some cases, the issue may be due to a misfiring cylinder. This can be caused by a variety of reasons such as worn spark plug wires or low compression in the affected cylinder. Have a mechanic perform a compression test to determine the cause.
