Why does my Vauxhall Insignia keep stalling?

I've been having issues with my Vauxhall Insignia stalling at unexpected times. I've had the fuel pump and spark plugs replaced, but it's still happening. What could be causing this and how can I fix it?

It's possible that the issue could be with your fuel filter. If it's clogged, it could be causing your car to stall. I recommend having it checked and replaced if necessary.

Check your battery connections and make sure they are clean and tight. Loose or corroded connections could be causing intermittent stalling. Also, have your battery tested to make sure it's holding a charge.

If you have a variable valve timing (VVT) engine, the solenoid could be malfunctioning and causing the stalling. Have a mechanic check it and replace if necessary.
