Seat Arosa rough running and misfire errors

I'm getting seriously frustrated with my 2000 Seat Arosa. It's got a gasoline engine and about 124652 km on the clock. Lately, the engine's been running really rough, like it's not getting enough fuel or something. The check engine light is on, and when I accelerate, it's jerky as anything. I scanned it, and it's throwing engine misfire errors. Could it be the fuel injectors? Or maybe the fuel pump is on its way out? I've even heard stories about the oxygen sensor or ignition coil causing similar problems. Any ideas before I lose my mind?

Sounds familiar. I had similar issues with my Seat Ibiza (same gasoline engine). Check the exhaust system for leaks. That was the culprit for me.

Really? A leak in the exhaust system? I wouldn't have thought of that. Where exactly was the leak in your case? And did you also have the check engine light on?

Yep, check engine light was on for me too. The leak was near the manifold, I think. It's like trying to run with a hole in your shoe – the engine can't breathe right. Honestly, I'd suggest getting it checked at a workshop. They'll be able to pinpoint the exact location and get it sorted properly.

Took it to the workshop and you were right. There was a leak in the exhaust system, just as you said. They fixed it, costing 265€. The car is running smoothly again. Thanks for the help.
