Nanni (Toyota) T4.200 Common rail idle speed problem

[Tondi]

Have just bought an Antares 760 with the Nanni (Toyota) T4.200 common rail engine.

The idle speed is too fast at about 820 but I cannot find a means of turning it down - no usual adjuster screw on the throttle linkage.

Being all electronic I suppose it is in the software and needs an agent's equipment to do so.

Has anyone had experience of this please?

Manual is here. It says idle speed is 700 to 750rpm which isn't far off what you're getting.

Edit: Also a link to a paid for workshop manual.

Edit 2: I see in another version of the manual that the idle rpm is 750 +/- 50. Which would be between 700 and 800. You don't seem to have a problem.

Thanks Clash, I already have the manuals. Yes it is close but I would still like to take it down a bit.

Does the workshop manual not cover it?

No it doesn't.

It's a 2.0 litre Toyota D4D engine, maybe something in the car/truck manuals ?

If you drop it any lower the engine will vibrate .
