Injectors are attached to the fuel rail with holders

Fuel constantly circulates around the circumference of the injector body, which avoids the formation of gas bubbles and facilitates starting a hot engine.

If the nozzle is clogged or fails, malfunctions are possible:

  • - unstable engine operation;
  • - difficulty starting the engine;
  • - increased engine idle frequency;
  • - stop the engine at idle;
  • - poor engine response;
  • - increased content of CO and CH in exhaust gases;
  • - glow ignition

To do the job you need tools: 10 tool sockets, TORX E12, screwdrivers

Using an ohmmeter, we check the resistance of the injector winding. The resistance should be 12 ohms.

We check the spray and flow of nozzles separately from the car.
