Disadvantages of the Isuzu 4ZE1 engine

- It is also very difficult to find a master who will undertake the repair of such a unit.
- The reason for floating engine speeds is most often the contamination of the throttle assembly.
- The fuel pump and the archaic ignition system have low reliability here.
- Periodically it is necessary to adjust the thermal clearances of the valves and change the timing belt.
