Discussion:
Revving on its own

I have a Linde H25T-03 which has started revving on its own - I have changed the accelerator potentiometer and module but truck is still doing same thing - it is only an increase in revs - not revving its head off.
Can anyone possibly pass on a few pointers - i have been told it could be the Llambda sensor?

Regards

Hi Chris, this is Rolf from South Africa. I have the same problem with my Linde Forklift 350H09111716. The engine starts beautifully but revvs up immediatly to full power.
You had the same problem with your machine. How did you solve it? what was the reason? Linde in Cape Town is closing down and I cant get any professional help from them.
Your help is much (!) appreciated
With kind regards
Rolf
