Why does my Vauxhall Insignia keep stalling while idling?

I recently purchased a used Vauxhall Insignia and I noticed that it occasionally stalls while idling at a stoplight or in traffic. What could be causing this problem and how can I fix it?

This could be due to a number of reasons such as dirty fuel injectors, a faulty idle control valve, or a clogged air filter. I would suggest taking your car to a mechanic for a diagnostic test to pinpoint the exact cause of the stalling issue.

Have you checked your spark plugs? Worn or faulty spark plugs can also cause stalling at idle. You can easily replace them yourself or take your car to a mechanic for assistance.

From personal experience, I've found that using a fuel additive can greatly improve the performance of my car and prevent stalling. Make sure to choose one that is suitable for your Vauxhall Insignia.
