Ioniq Hybrid Stalling and Fuel Consumption

I'm having trouble with my 2016 Hyundai Ioniq hybrid. It's got about 106k kilometers on it. Recently, I've noticed some worrying signs: my fuel consumption has gone up, the engine feels sluggish, and it sometimes stalls when idling. Plus, there's a bit of smoke coming out when I accelerate. Could this be related to a faulty injection system? I've checked the basics, but I'm wondering if it might be a cable or plug issue with one of the components. Anyone else experienced this?

A 2016 Hyundai Ioniq hybrid with 106,000 kilometers is experiencing increased fuel consumption, sluggish engine performance, stalling when idling, and smoke during acceleration. These issues may be linked to a faulty injection system, possibly due to a defective plug connection causing misfires. A professional diagnosis confirmed the problem as a faulty plug connection on the injection system, which was subsequently repaired.

I also drive an Ioniq hybrid. Your symptoms sound familiar. Are you certain that the air intake system is free of obstructions?

Good point. I did check the air filter, but I haven't looked closely at the entire intake system. What sort of obstructions are we talking about, and how would that impact the fuel injection?

In my case, the performance degradation and stalling were due to a defective plug connection causing misfires. It is advisable to seek a professional diagnosis to confirm.

Thanks for the advice! Turns out you were spot on. Took it to the shop, and it was indeed a faulty plug connection on the injection system. Cost me 95€ to fix. Appreciate the help!
