Yes! There is a misfire. It's like the car stumbles a little when I accelerate. What did you do to fix it? I'm worried this is going to cost a lot.

The misfire confirms it! Based on your symptoms, it sounds like a fuel injection issue, likely dirty. My mechanic confirmed it by checking the injectors; the spray pattern was all wrong on one. You'll probably need to visit a workshop.

I took it to the workshop. They checked the injectors and, as you suspected, one was defective. It cost me 515€ for the replacement, but now it runs like new!

That sounds familiar. I also own a Chevrolet Sail and had a similar issue not too long ago. Poor starting, increased fuel consumption, reduced power, and uneven idling were all present. Did you notice anything else, like a slight misfire, especially when accelerating? It almost felt like the engine was hesitating.
