- unstable engine operation;

- engine idling;

- increased speed of rotation of the crankshaft at idle;

- the engine does not develop full power, insufficient engine pick-up;

- jerks and failures in the engine operation when the car is moving;

- increased fuel consumption;

- increased CO and CH content in exhaust gases;

- hot-pot ignition due to violation of the tightness of the injectors.

Removing the nozzle from the fuel ramp

In the same way, we remove the remaining nozzles

Check the resistance of the nozzle winding.

The resistance of a serviceable nozzle should be 0.013-0.016 kOhm. If the winding resistance does not correspond to the norm, replace the nozzle

Checking the nozzle for spray should be checked on special equipment, such a check on a car is very flammable.

Pry with a screwdriver and remove the O-rings

Replace the nozzle O-rings regardless of their condition.

We install the injectors and the fuel ramp in reverse order.

After assembly, we check the connections for tightness.
