5.37. Technique of search of malfunctions

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

1. Electric food

  • Battery
  • Burned-through crossing point
  • Fuse

2. Connections with "weight"
3. Supply of fuel

  • Toplivoprovod
  • Fuel filter
  • Fuel pump

4. Ignition system

  • Spark plug
  • High-voltage wires
  • Ignition coil

5. System of decrease in toxicity of the fulfilled gases

  • System of ventilation of a case
  • Vacuum leak

6. Others

  • Installation of a corner of an advancing of ignition
  • Frequency of rotation of idling
Malfunctions of MFI system are often caused by bad contacts in sockets of a plait of wires. Therefore check reliability of connection of all sockets.
