Why does my Vauxhall Zafira Life's engine keep stalling while driving?

I have a 2010 Vauxhall Zafira Life and recently I've noticed that while I'm driving, the engine will randomly stall and lose power. This has happened on both city streets and highways. What could be causing this issue and what steps can I take to prevent it from happening?

First and foremost, it's important to know that engine stalling can have multiple causes. It could be due to a faulty fuel pump, fuel filter, or ignition system. I would recommend checking these components first.

Another possibility is that the idle air control valve (IAC) is dirty or faulty. This valve controls the amount of air entering the engine at idle, and if it's clogged or malfunctioning, it can cause stalling. Clean or replace the IAC if necessary.

If the stalling only happens when the engine is cold, it could be due to a malfunctioning engine coolant temperature sensor. This sensor helps regulate the fuel and air mixture and if it's not working correctly, it can cause stalling. Consider having this sensor checked and replaced if needed.

It's also a good idea to have the computer system scanned for any error codes. These codes can give a better indication of what the issue could be. You can either take your car to a mechanic or use a code reader yourself.

As a preventative measure, make sure to keep up with regular maintenance such as oil changes and tune-ups. This can help prevent stalling issues in the future.
