Disadvantages of the C14NZ engine
- The ignition system delivers the most problems, the spark constantly disappears here;
- The search for the cause should start with the cover of the distributor, then look at the candles and wires;
- Monitor the condition of the timing belt, its resource is 60 thousand km, and when it breaks, the valves bend;
- All kinds of electronic sensors often fail, and especially the lambda probe;
- The thermostat, the fuel pump in the tank, the idle speed controller have a modest resource.
