Aveo injection system issues
Summary of the thread
A 2013 Chevrolet Aveo with 175,235 km is experiencing issues with the injection system, leading to higher fuel consumption, reduced engine power, stalling at idle, and smoke during acceleration. The problem was traced to a corroded plug on one of the injectors, which was resolved by cleaning and replacing a short section of the cable. This highlights the importance of checking simple connections and components when diagnosing similar issues.

Cleaning the MAF sensor is a good shout, I'll give that a go. Regarding the injector plugs, how exactly did you test the voltage? Did you just probe the wires with the engine running, or is there a specific way to do it? I'm a bit worried about frying something if I do it wrong.

Yeah, you gotta be careful. I used a multimeter set to DC voltage, and probed the terminals on the injector plug with the engine running. You should see a voltage reading when the injector is supposed to be firing. If the voltage is erratic or non-existent, that's a sign of a bad connection or a faulty injector. Honestly, though, if you're not comfortable doing that, it might be worth taking it to a workshop. Electrical gremlins can be a real pain to track down.

Cheers for the advice! I took it to the workshop, and you were spot on. Turns out it was a corroded plug on one of the injectors. They cleaned it up and replaced a short section of the cable. Cost me 95€, but at least it's running smoothly again. Lesson learned: always check the simple stuff first!

Sounds rough. I had a similar experience with my old Peugeot 307, but it was a diesel. Same symptoms though – rough idling, power loss, and the fuel consumption was insane. In my case, it turned out to be a dodgy connection to the fuel injector. Did you check the voltage at the injector plugs? Sometimes a multimeter can tell you if you're getting a consistent signal. Also, have you tried cleaning the mass airflow sensor? That can cause similar issues.
