Ignition coils and spark plugs were actually the first things I checked – all seem to be in good shape. I even swapped them around to see if the misfire followed, but no luck. So, you reckon it still could be related? What was the eventual fix for your Astra?

Ah, so you've already been down that road! Fair enough. In my case, it ended up being a faulty fuel injector. The garage diagnosed it pretty quickly, but it wasn't cheap. I ended up paying around 450€ for the repair if I remember correctly. Considering you've already eliminated the ignition system, it might be worth getting the injectors properly tested. A compression test won't hurt either.

I took it to the workshop, and you were spot on – faulty fuel injector! All in, the repair came to 515€. Runs like a dream now. Appreciate the help!

Sounds frustrating! I had a similar issue with my old Opel Astra, although the symptoms weren't quite as pronounced. Check engine light, rough idle, and occasional jerking. Did you check the ignition coils? What about the spark plugs? They might be the culprit.
