Poor fuel economy
Check engine light on
Black smoke from exhaust on acceleration

Thank you for your quick reply. I have had the car for about 6 years and the current mileage is 141833 km. The last inspection was last year, so quite a long time ago. I will probably visit my garage and have the lambda sensor checked. Hopefully it won't be that expensive, but I fear the worst. I'll probably need a new catalytic converter too... Thanks again for your advice. You've helped me a lot!

No problem, always welcome! At your current mileage, it's actually not unusual for individual parts to give up the ghost or need cleaning. Last year's inspection was a while ago, but it's not a cause for concern as long as you don't completely skip the maintenance intervals. Remember, the lambda sensor is only one of many possible causes for the symptoms you mentioned. It could just as easily be a problem with the injection system, the spark plugs or the air filter, but your car definitely belongs in the workshop. I'll keep my fingers crossed that the costs won't be too high. Let us know what comes out! With my Peugeot it was actually the lambda sensor at the time, but that doesn't necessarily have to be the case with you. Hope this helps you and have a good trip!

I have a Peugeot 207, for the past 6 months my car has been struggling to idle when cold. It is misfiring and ends up just coming to a complete stop, only when it reaches temperature it will stop however if I drive off as soon as I start it I will put my foot down and nothing happens then all of a sudden it accelerates harshly. I’ve plugged in my obd reader and reeds a code to do with 02 sensor cuiruit bank 1 sensor 1. I’ve done research and has actually led to the ECU. I don’t deal with cars I’m a plant mechanic but would love to hear what advice is given.

Start by checking the condition of your spark plugs and ignition coils, as these can cause misfiring and poor idling when cold. If they are worn or damaged, replacing them might resolve the issue. Since you have an OBD code related to the O2 sensor, inspect the wiring and connections for any damage or corrosion. If the problem persists, it might be worth having a professional check the ECU and related components. Let me know how it goes or if you have any further questions!
Hi, well I had a similar problem with my 2005 Peugeot 1005, I'm not a car expert but have some experience from other similar situations. The black smoke along with the other symptoms does indeed indicate that your lambda sensor could be dirty or clogged. It was exactly the same problem with my car. I had to take the car to the garage and they cleaned the ceramic inside the lambda sensor, which cost 375 euros. Could you perhaps give more details about your car? For example, how long have you had it, when was the last inspection, etc.? This could help me to better tailor my advice. Hope that helps!
