Seat Ateca Gasoline Engine Combustion Misfires

Engine misfiring can be a real pain! I had a similar issue with my old Renault Megane. Check engine light, rough idle, the whole shebang. Have you checked the spark plugs? Sometimes it's the simplest thing.

Thanks for the quick response! Spark plugs were replaced recently, so I don't think that's the issue. The engine misfiring seems more pronounced under acceleration. Could it still be something spark-related if the plugs are new?

In my case, the spark plugs were fine too, but the issue was still fuel related! The mechanic told me it was like a clogged artery, not letting enough fuel in. If it feels worse when accelerating, it could be a fuel delivery issue, like a fuel injector problem. I'd get it checked by a workshop. They can run proper diagnostics and pinpoint the exact fuel injector that's causing the engine misfiring.

Took the Ateca to the shop, and you were spot on! It was a faulty fuel injector. Replaced it, and the car is running smoothly again. Cost me 515€, but it's worth it to have it back to normal. Thanks again for the help!
