What could be the cause of a misfiring engine in a Vauxhall Astra?

My Vauxhall Astra's engine has been misfiring recently. I checked the spark plugs and they seem fine. What could be the cause of this issue?

One possible cause of a misfiring engine in a Vauxhall Astra could be a faulty ignition coil. It is responsible for delivering the spark to the spark plugs and if it is malfunctioning, it can result in a misfire. I suggest getting it checked and replaced if necessary.

Another common cause of misfiring in a Vauxhall Astra is a clogged fuel injector. This can happen due to buildup of debris or dirt in the fuel system. I recommend getting the fuel injectors cleaned or replaced.

A dirty air filter can also contribute to a misfiring engine. If the air filter is clogged, it can disrupt the air-fuel mixture and cause a misfire. I suggest checking and replacing the air filter if needed.
