Thanks for the quick reply! No, I haven't checked the oxygen sensor yet. Where is it located, and is it easy to test? Could a dirty throttle body or a leak in the intake manifold cause similar problems? I've been trying to avoid taking it to the shop, but I'm starting to think it's inevitable.

I wouldn't mess with the throttle body or intake manifold just yet. In my case, it turned out to be the fuel injectors. I'd advise taking it to a workshop; they'll be able to diagnose the issue properly. It's better to be safe than sorry when it comes to the fuel system.

Okay, thanks for the advice. I took it to the workshop, and you were right - it was a defective fuel injector. They replaced it, and the car runs like new again. The repair cost me 515€. I appreciate the help!

Sounds familiar. I had similar symptoms on my Linea. The check engine light was on, and it felt like the car was struggling to accelerate smoothly. Have you checked the oxygen sensor? It might be faulty and sending incorrect readings.
