  • The reason for unstable idling is the contamination of the idle speed controller or crankcase ventilation;
  • The exhaust manifold has low reliability, often it simply bursts;
  • The weak point in the electrical part is the camshaft position sensor;
  • The timing belt resource is about 60 thousand kilometers, and when it breaks, the valves always bend.
