2. Tighten the bolts and nuts.
Checking the injectors
The injectors are checked by listening to clicks through a stethoscope or a long screwdriver, measuring the electrical resistance of the winding, which should be 13–16 Ohm at 20°C, and also by the torch on the stand (performed in a car service).
Warning! It is forbidden to test the injectors with 12 V battery voltage, otherwise they will fail.
