Skoda Superb Engine Problems

Rough running and a check engine light usually point to a few common things. Since you mentioned misfires, I'd start by checking your spark plugs and ignition coils. Have you scanned for specific error codes? That'll give you a better idea of which cylinder is misfiring. A bad fuel pump can also cause those issues, but it's less common. Has it been making any weird noises lately?

Haven't checked the error codes yet, but I did think about the fuel pump. How would I know for sure if it's the fuel pump versus something else?

A faulty fuel injector can definitely cause misfires. If you can get the error codes read, that would confirm it. A mechanic can also test the fuel pressure and injector spray pattern to be certain. It's best to get it sorted quickly, as running with misfires can damage the catalytic converter. Good luck.

Took her to the shop. It was the fuel injector like you thought. 515€ later, she's running smooth again. Thanks for the help!
