Lova rough idle and misfires

Hi, I'm having some trouble with my 2019 Chevrolet Lova, gasoline engine. It's got 224546 km on it. Lately, it's been starting poorly, fuel consumption is up, engine power feels reduced, the idling is uneven, and sometimes it even stalls at idle. I suspect a defective injection nozzle, maybe just dirty. Any ideas?

Sounds familiar. I've got a Lova too, and I had similar issues a while back. Misfires, rough idling, all that jazz. Made me think the car was about to give up. Have you checked for any error codes? When my injector went bad, it threw a code pretty quickly.

Thanks for the reply. I haven't checked for error codes yet. What exactly did you do to fix it? Was it just one injector, or all of them? And how much did it set you back?

Okay, so mine was definitely a faulty injector. Symptoms were the same as yours. I'm no mechanic, so I took it straight to the workshop. They confirmed it and replaced the bad injector. Honestly, unless you're experienced with fuel systems, I'd recommend getting it checked out by a professional. It's not worth risking further damage.

Took your advice and went to the workshop. They confirmed it was a defective injector. Replacement cost me 515€. Runs much better now, so thanks for pointing me in the right direction!
