Visual check


    To begin with check up air lines on tightness! It is necessary to check all hoses – from a thick sleeve of an air inlet to thin vacuum hoses. Whether as it should be sealing linings under the starting fuel valve and on впрыскных atomizers, and also фланцевые linings of inlet channels? Not tight places open access to not considered air, that is air which is not considered by air flowmeter and consequently essentially disturbs to mix preparation. The mix неконтролированно is impoverished. A consequence of it are malfunctions in work of the engine and rough idling. Whether it is possible to distinguish негерметичность топливопровода? Whether tips of wires have been repeatedly separated and again connected? Corrosion or inept actions can lead to insufficient contact. Attentively consider tips of separate components of system of injection. Uvulas of contacts do not bend, but only process a contact spray.
