Search and elimination of malfunctions

By search of malfunctions of the engine begin with check of working capacity and survey of the basic systems. If the engine work, unstable frequency of rotation of a cranked shaft idling or insufficient acceleration is broken, check up following basic systems:

    An electric food
    • the Battery
    • the Burnt through crosspiece
    • the Fuse
    Connections with "weight" Fuel giving
    • the Fuel filter
    • the Fuel pump
    Ignition system
    • the Spark plug
    • High-voltage wires
    • the ignition Coil
    System of decrease in toxicity of the fulfilled gases
    • ventilation System картера
    • Vacuum leak
    • Installation of a corner of an advancing of ignition
    • Frequency of rotation of idling

Malfunctions of system MFI are often caused by bad contacts in sockets of a plait of wires. Therefore check up reliability of connection of all sockets.
