Hi to all
My 2002 when trying to idle will hunt with the revs going from 750 to 1200 and back again occasionally the engine will slow until it nearly stalls at which point there is a "clunk" and the revs pick up again. When the engine is run at anything above 1200 rpm it is fine and runs smoothly.
I have watched an engineer adjust the volume screw and the engine will stop if it is screwed in but the engine will only idle at 750 rpm and no higher if it is screwed out.
the governor looks ok as he had the cover off and all the springs were in place.
As far as I'm aware the injectors have been overhauled the fuel tank has been cleaned and there are new fuel filters in the line.
I also noticed that when the return pipe from the engine to the tank was removed the fuel syphoned out of the fuel tank. I have also noticed that there is no "squeak" comming from the mechanical lift pump.
Having read through a lot of posts on here would i be right in thinking there is an air leak somewhere in the system that will cause the hunting or is it something more profound.
I would welcome any thoughts the panel might have.
