Have you checked the coolant level in rdiator?
Have you tried to retrieve for trouble codes?

I also have a H-100 Diesel. Mine is a 1998. To the left of the steering wheel and a little below is a ****. On the **** are two parallel lines and an angle line in between (let me see if I can make it on the keyboard). Kind of like an equals sign with this in between . Im not sure if the 2000 has this ****.
If the **** is turned to the right, it will make the engine rev at a higher RPM. If you have this ****, try turning it to the left slowly. Once you turn it, it takes the engine a second to respond. If this is the reason your engine is rev-ing to high, then you can adjust it to the level you want.
