Special tools and equipment

NOTE: Faulty injectors can cause the following malfunctions:
- Engine runs rough

Faulty injectors can be located by loosening the high pressure line union on each injector in turn, with the engine running at a fast idling speed. If the engine speed remains constant after loosening a line union, this indicates a faulty injector.
