Thank you so much. My problem is that my car is not serial as before. It accelerates slower than 1.4 vehicles. He also started to burn too much. & nbsp; There is a well-known master in Bursa industry, I go to him for a long time. The Egr valve said it was faulty, so I said let's change it. It has been two months, still no parts. He started talking on the phone as if he was repellent, so I don't go to that master anymore. Some friends were suggesting the manifold cleaning, I said let's do it, you hear and hear from the internet, this is the catalyst vehicle, the manifold will not fill. But my friends studying in the Department of Automotive at the University say the opposite, I also saw photos of the manifold cleaning of a 2008 model focus, it was officially like a coal mine. So I can't trust this master. Anyway, I extended the word very much :) The essence of the word, the vehicle is not serial and it burns a lot, what can I do ?? & nbsp;

& nbsp; & nbsp; Meanwhile, the vehicle is 2003 model 307 2.0 HDI .. At 151,000 km & nbsp;
