hello pejo partner 2003 hdi.2.0 diesel vehicle suddenly cut off from gas Izmir does not even come to 3000 cycles in 1st gear The vehicle feels like it is pulling from behind, it comes to 3000 revolutions in 3 gears but it did not do again in the morning. what could be the fault please help

spark plug, spark plug cable, Coil

I don't think they were gone

There is a situation that causes the turbo to not activate or deactivate, hodja. Connect the pc and check the error code. Meanwhile, in diesel vehicles, coil etc. No way. it just glow plug. Also, have the solenoid valve and the air doser (flow meter) checked.
