Check and adjustment of turns and quality of mix of idling

THROUGH EACH 30 000 KM (18 000 MILES) OF THE RUN

 PERFORMANCE ORDER

1. Before starting installation of turns and qualities of mix of idling perform the following preparatory procedures:
   -  Check a condition of spark plugs the size of interelectrode gaps (see Replacement of spark plugs);
   -  Check correctness of adjustment of a cable of an accelerator (see the Power supply system - petrol models);
   -  Check a state and reliability of connection of ventilating hoses of a case of the engine (see Check of serviceability of functioning of systems of decrease in toxicity of the fulfilled gases);
   -  Check a condition of the filtering air cleaner element (see Replacement of the filtering air cleaner element);
   -  Check a condition of components of system of production of the fulfilled gases (see Systems of decrease in toxicity and production of the fulfilled gases);
   -  If violation of stability of turns of the engine takes place, check compression pressure in cylinders and valvate gaps (see. The repair procedures which are not demanding extraction of the engine from the car - petrol engines);
   -  Make sure that the control lamp of system of injection of fuel/ignition is disconnected (see the Power supply system - petrol models).
2. Make a short trip during which the engine has to be heated-up up to the normal working temperature on the car.

Adjustment has to be made within the first two minutes after return from a trip (you do not suppress the engine). Wait for shutdown of the fan of the cooling system. having several times lifted engine turns to value of 2000 rpm, remove excess fuel of their inlet pipeline, then again dump turns to single.

3. Rather skilled amateur mechanic, having the necessary equipment (a qualitative tachometer and accurately calibrated gas analyzer) is able to execute by own forces verification of the contents in the fulfilled gases of monoxide of carbon (SO). However, in case of detection of surplus WITH, the car should be driven away for adjustment on car repair shop.
4. On the models equipped with a control system of the Magneti-Marelli engine adjustment of quality of mix of idling (contents level WITH in the fulfilled gases) it can be executed only by reprogramming of ECU of a control system with use of the special electronic equipment connected to the diagnostic socket (see the Power supply system - petrol models).
5. On all other models this adjustment is not provided and its performance is not possible. The deviation of under control parameters (turns of idling and concentration WITH in the fulfilled gases) from norm demonstrates violation of serviceability of functioning of a control system of the engine. In this case the car should be driven away for performance of more detailed diagnostics and necessary repair on car repair shop (see the Power supply system - petrol models).
