CHR Engine Misfires

I had something similar with my Opel Insignia, though it's a different car and engine. Rough running and check engine light. Have you seen any changes in fuel consumption or weird smells from the exhaust? Maybe check the ignition coils? They can cause misfires without throwing a code right away.

No change in fuel consumption or smells. I haven't checked the ignition coils yet. Could a bad coil really cause the jerking when accelerating? Or could it be a bad injector?

Yeah, a failing ignition coil can cause jerking, especially if it's an inconsistent spark. A bad injector is also possible. You should get it checked by a workshop. They can run diagnostics to find the problem. Better to catch it early before it causes more damage.

Thanks for the help. I took it to a mechanic, and it was a defective injector. The repair cost 515€.
