N300 engine misfires

I'm having trouble with my 2015 Chevrolet N300, gasoline engine. It's got about 184000 km on it. Lately, the engine's been running rough, and the check engine light keeps popping up. I also feel a jerking motion when I accelerate, and the engine power seems reduced. I think it could be related to combustion misfires. Any ideas?

A 2015 Chevrolet N300 with approximately 184,000 km is experiencing rough engine performance, a check engine light, jerking during acceleration, and reduced power, likely due to combustion misfires. The issue was traced to a defective fuel injector in one of the cylinders. Replacing the faulty injector resolved the problem, restoring the vehicle's performance.

Sounds familiar. I had a similar issue with my N300 a while back. Same symptoms – rough idle, check engine light, and all. Misfires, right? Did you manage to pull any error codes? What cylinder is misfiring?

Yeah, combustion misfires for sure. I checked the error codes, and it seems like the misfires are coming from one of the cylinders. What did you end up doing to fix the same issue?

I took it to a trusted workshop. It turned out one of my fuel injectors was defective. They replaced it, and the problem vanished. Cost me around 500€, but it solved everything. I suggest going to a workshop.

Thanks, that's helpful. I'll take it to the shop and have them check the injectors. You were right! Cost me 515€, but now it runs fine!
