307 HDI, falling from traction

Merhabalr friends, I have 2003 model 307, 2.0 HDI. It seems to me that my vehicle has started to fall out of traction for the last 2 months, it does not seem to have any old attacks. In the past, when I pressed the gas, I used to stick to the seat, now as if I was putting the gas in 1.3 cars. The other day, I said, let's make a trial with my father's 1.4 HDI Citroen Xsa, officially raising speed faster than my car. Also, he started to burn the fuel too much. I did not calculate like a man, but as far as I can see, it goes around 200 km from the city with a diesel of 100 TL, I would never see less than 300-350 before. In the last two months, engine oil (I put Castrol EDGE 5w-40), diesel filter and air filter, as well as the front wheel balls have changed, I don't think the problem is caused by them but I wanted to say that maybe an idea would occur. If I used injector cleaner or read in Forum before, they suggested manifold cleaning for a similar problem. Does it work for me too? & nbsp; I am waiting for an answer from experienced friends, I started to get very cold now.

you said the front wheel balls have changed, maybe the vehicle's wheels are not turning freely. How is the flow of the car when the bay is wasted down? or can I lift a tire with a jack? a possibility.

Have you connected the car to the computer and looked for any errors there? I also experienced the problem of falling out of traction similar to what you once said during the flow meter failure (flow meter is a part that passes air and measures like air filter, the oxygen entering the engine when it makes the wrong measurement is calculated incorrectly and the engine may fall off the traction). As you said, although I have changed the filters, it did not improve, but the last time it was connected to the computer, the fault appeared. Maybe you have a similar situation. Hopefully you will get it done in a short time. & Nbsp;

The downhill flow is not bad, it does not seem to be strained. It was connected to the computer last month, but there was no fault, no error. As you said, is there anything related to the sensors? Or they suggested the manifold cleaning, would it work

The problem is fixed, I have similar things in your car now.
