Peugeot 4007 Injection Fault

I have a 2011 Peugeot 4007, gasoline. I've noticed increased fuel consumption, reduced engine power, engine stalling at idle, and smoke from the exhaust upon acceleration. Could this be a faulty injection system, perhaps a defective cable or plug connection?

Faulty injection system on the 4007, eh? With those symptoms, it sounds plausible. Have you checked the cable and plug connections yourself? Are there any visible signs of damage or corrosion?

I've done a quick visual check, but I lack the tools for a thorough examination. Is there a recommended method or tool for checking these connections without taking everything apart?

Without proper tools, it's tough to be certain. Given the symptoms and your mileage, plus potential connector issues, I'd advise getting it checked professionally before things worsen. Could save you more trouble down the road.

I had it inspected by a technician. It was a defective electrical connector in the injection system, as suggested. The 95€ repair fixed the problems. Thanks for the insights.
