Antipollution Fault and Idle Imbalance

I have owned 2007 model Peugeot 207 1.4i for a while, I have not had any problems since the day I bought the car ... I had a zero engine, I changed the ignition coil, I changed the spark plugs, the press lining I changed it, I changed the radiator, I replaced the upper oxygen sensor. These are the things that come to my mind; If I force it, it will be more ... & nbsp;

Antipollution Fault cannot be destroyed anymore, and now when I press the clutch, the vehicle started to stop. Given the error codes, P0141 and P1327 are giving. I ask you, can you give me a special service recommendation that can solve this job professionally, not by trial and error method? It would be nice if Istanbul is on the Anatolian side because I'm in Tuzla. If you say you cannot solve it other than the authorized service, I will go there now ... & nbsp;

I've been searching for a long time the problem of the vehicle; I found the solution, I would like to share with you. I was dealing with the nightmare P0141 error and the speed ripple at idle. Almost all masters stated that the P0141 error from the post-catalyst oxygen sensor should be replaced or canceled. But was the sensor really bad or was it just doing its job? I had an old elm327 socket and the voltage values of the oxygen sensor after the catalyst could be checked. The sensor was intact and was delivering voltage; however, the ECU was giving an error when it was out of the reference values. Firstly, I had a catalyst control; the catalyst was hollow. After installing the catalyst, the related error decreased but still appeared. One day, when the car did not start, when he looked at the error levels, he saw that there was a crank sensor malfunction; When I replaced it with the original part, I completely got rid of the P0141 error. When I replaced all the ignition parts (coils, spark plugs, etc.) before, I did not receive any errors. Not every sensor error is caused by sensor breakdown; it can also be caused by some parts not doing their job. I would like to note that fuel values are also decreasing. & Nbsp;
