Hello, I have a 2.0 liter 407 diesel car, the car does not eat gas, so often it shifts, and when you go 100 km fast, you take your feet out of the gas and press it again. as printed. I got to the service, I did not have any problems on the computer, I changed the injectors, still doing the same. I wonder if you can help.
thanks

I would say the diesel quality may be low, but you even replaced the injectors. I suppose you pay attention to the diesel you get, right? but still don't ignore this fuel situation ...

I did not use a diesel engine, but there was also a problem in this vehicle.

actually, every diesel does not attack as soon as it presses on the gas, it will be activated with turbo power after 1 second. Could the catalyst be blocked?

If it burns too much in its fuel, the catalyst is blocked, but the diesel car does not immediately absorb the gas, it should have been an average of 2 seconds, was it not before?

a bit of possibility, but the dump valve mechanism inside the turbo may have been malfunctioning. ensures that the exhaust gas does not come out of a separate channel and get into the exhaust path when it comes out of the gas. This valve closes when the gas is pressed and the exhaust gas of the turbine is filled and the pressure is increased.
If there is no problem when the gas is pressed continuously, if this is done when the first time is pressed, this is the first thing that came to my mind.

Yes, I am paying attention to the diesel, but it is like a misfire. It is not like taking it in the night, so you cannot drive the car.

So this was not a problem, and if there was a catalyst obstruction, would that be misfire in the car?

So there is no such problem, when I say the problem of taking the gas, the pedal becomes idle.
if it is both catalyst and the server does not show the error in the service
