  • Throttle or EGR contamination is the main cause of floating rpm;
  • The thermostat, pump and engine mounts do not have the highest resource here;
  • After 200-250 thousand km, an oil burner and timing chain stretch are very common;
  • There are no hydraulic lifters here, so you need to adjust the valves every 100,000 km.
