Spark injection system issue

My 2021 Chevrolet Spark (gasoline engine) has 170175 km on it and I suspect an injection system problem. Symptoms include higher fuel consumption, reduced engine power, and occasional stalling at idle. I've also noticed some smoke when accelerating. I've checked the usual suspects, but I suspect a defective cable or plug connection. Any ideas?

Sounds familiar. I had similar problems with my Spark. Fuel consumption went through the roof, and the engine felt sluggish. Have you checked all the connections related to the fuel injectors?

Yes, I've visually inspected the connectors and wiring as best as I can. I'm not sure where to look in more detail. Is that what you were referring to, or something else?

Yep, that's what happened to me. The connection seemed fine at first glance, but it was slightly loose. I'd recommend taking it to a trusted workshop. They'll diagnose it properly. It's worth the peace of mind.

Thanks for the advice. It turned out to be a defective injector plug, just as you suspected. A replacement and diagnosis cost me 95€. Now it runs perfectly.
