3.6.3. Jerks at the established movement

Such jerks happen are caused by malfunction of system of ignition more often. Diagnostics and repair (section 10 "Electric equipment" see) are necessary. In a way it is possible to try to execute independently following:
– Attentively examine подкапотное space. Switch off ignition and check up reliability of fastening and landing of all wires and sockets at the coil of ignition and high-voltage wires. Start up the engine and listen to its work: a crash at power-current breakdown on weight weak, but distinct. In full darkness it is well visible a spark at breakdown;
– Replace spark plugs irrespective of their condition and run. Pay attention to a condition of candles: if it does not correspond to norm, probably, it is necessary to repair the engine or its systems.
Failure of the gauge of position throttle заслонки can be the specific reason of jerks at the established movement of the car with инжекторным the engine. The additional symptoms confirming malfunction of this gauge:
– Non-uniform work of the engine idling;
– Decrease in the maximum capacity of the engine.
The gauge not folding and consequently неремонтопригоден. If malfunction of the gauge (Check and replacement of gauges of a control system with the engine see) is revealed, replace the gauge in gathering.
