Why is my Vauxhall Astra stalling?

I've noticed that my Vauxhall Astra has been stalling frequently and I'm not sure what the problem could be. It usually happens when I'm driving at low speeds, like in traffic or when approaching a stop light. What could be causing this issue and how can I fix it?

There could be a few potential causes for your Vauxhall Astra to stall. It could be an issue with the fuel system, such as a clogged fuel filter or a faulty fuel pump. It could also be a problem with the ignition system, such as a bad spark plug or a malfunctioning ignition coil. I recommend taking your car to a mechanic to have it diagnosed and repaired.

Another common reason for stalling in Vauxhall Astras is a problem with the idle control valve. This component controls the engine's idle speed and can become dirty or fail over time. Cleaning or replacing the idle control valve should solve the stalling issue.

If your Vauxhall Astra runs on diesel fuel, stalling could be caused by a clogged diesel particulate filter. This filter is responsible for trapping harmful emissions, and when it becomes clogged, it can cause stalling. A mechanic can clean or replace the filter to solve the issue.
