206 HDI misfire issue

Peugeot 2006-206 1.4 Hdı Feline If you use my car at high speed when going off the highway, it makes a misfire once in a while at low speed, I took the car to the master today. They said it might be on the pump or injector, but I don't know.

For the past, I recommend reducing your font size a little. It is not read on mobile properly.

Thank you, thank you for writing from PC, why is it so normal on mobile?

Check the crank speed sensor at my teacher. Injectors - can be in the pump. Have the turbo hoses checked, leak etc. Is there?
