Vauxhall Adam rough idle and poor starting

Hi, I'm having some trouble with my 2019 Vauxhall Adam (gasoline engine). It's got 235306 km on the clock. Lately, it's been starting poorly, fuel consumption seems higher, and engine power feels reduced. I've also noticed uneven idling, and the engine even stalled a couple of times while idling. Could a dirty injection valve be the problem, leading to a defective injection nozzle?

Sounds familiar! I had a similar issue with my Adam. Rough idle, poor starting, the works. Have you noticed any misfires, especially when the engine is cold?

Thanks! I haven't specifically observed misfires, but is that definitely the injection at fault?

In my case, the symptoms were almost identical, and yes, it turned out to be a faulty injector. To be absolutely sure, though, you really need to get it checked at a workshop. Cost me 515€ to get it sorted.

Understood. Thanks for the advice! I'll take it to a workshop to get the injection nozzles inspected. Hopefully, it's a straightforward fix, and thanks again for the information about the potential cost, very helpful!
