Visual check

 PERFORMANCE ORDER

  1. For a start check air ducts for tightness! It is necessary to check all hoses – from a thick sleeve of an air inlet to thin vacuum hoses.
  2. Whether as it should be sealing laying under the starting fuel valve and on vpryskny nozzles, and also flange laying of inlet channels?
  3. Untight places open access to unaccounted air, that is air which is not considered by an air flowmeter and therefore significantly prevents mix preparation. Mix is nekontrolirovanno impoverished. A consequence of it are malfunctions in operation of the engine and uneven idling.
  4. Whether it is possible to distinguish leakage of a fuel-supply line?
  5. Whether tips of wires
  6. were repeatedly separated and again are connected? Corrosion or inept actions can lead to insufficient contact.
  7. Attentively consider plugs of separate components of system of injection. Do not bend uvulas of contacts but only process contact spray.
