fast idle

Post by straggler » Sat Oct 14, 2017 11:32 am

I have a 96 406 XUDT with the Bosch fuel system.

The tickover speed is high (around 950rpm) and I can't adjust it out. Bizarrely, it drops to around 800rpm when at high altitude (like at the top of a Norwegian mountain).

Is there anything that's not the tickover screw I could check?

Does this pump have an anti stall adjustment? if so it could be that its set to high. Could be that was only CAV pumps.
