What can cause the engine malfunction in a Vauxhall Insignia?

I have been experiencing frequent engine malfunctions in my Vauxhall Insignia and I can't seem to pinpoint the issue. Can someone help me troubleshoot and figure out the possible causes?

Hi John, there are a few common issues that can cause engine malfunctions in the Vauxhall Insignia. Some possible causes could be a faulty spark plug, a clogged air filter, or a malfunctioning fuel injector. It's best to take your car to a mechanic to diagnose and fix the problem accurately.

Hey John, have you checked your car's battery? Sometimes a weak battery can lead to engine malfunctions. I suggest testing the battery for any issues before looking into other possible causes.

Hi there, I had a similar issue with my Insignia and it turned out to be a faulty oxygen sensor. I highly recommend getting it checked and replaced if necessary.
