C70 rough running and stalling

My 2013 Volvo C70 with a gasoline engine is running rough, especially at idle where it sometimes stalls. It's got about 90k km on the clock. The check engine light is on, and the car jerks when accelerating. I suspect a defective cable or plug connection. Anyone experienced something similar?

A 2013 Volvo C70 was experiencing rough running, stalling at idle, and jerking during acceleration, with the check engine light on. The suspected cause was a defective cable or plug connection. A suggestion was made to check the ignition coils, as similar symptoms were resolved by addressing a coil failure. After diagnostics confirmed a misfire, replacing the defective ignition coil resolved the issue, restoring smooth operation.

I had similar symptoms with my C70. Does it feel like a misfire? Check your ignition coils. Sounds like that could be the culprit.

Thanks for the tip! How did you figure out it was the ignition coils? Did you do any vehicle diagnostics before?

Yes, the diagnostics pointed towards a misfire. I recommend going to the workshop. It could well be a coil failure.

Thanks a lot for your help! It was indeed a defective ignition coil. The repair, including parts and labor, cost me around 95€. Runs smoothly again!
