Quick fix would be turning your engine on and off.Each cycle will reset your speedo by five miles an hour.Do this until your speedo is back to "0".

Smithy, that did it.
It was quite simple.
It seems like there are alot of gremlins in these trucks.
Now I have the windshield wiper gremlin.

turning the ingnition on and off will only get it back down to zero, but not keep it there. Every time you drive it will work it's way back up. Need to get it rebuilt, I've had it happen to two of my past H2's.

The wiper thing is an easy fix, just be careful with the clips on the cowl, they are a pain and break easy.

PaHumBug,
I am probably jinxing myself, but so far so good. I have clocked it against my GPS speedo app and each times comes back on the mark.

So..... Hopefully it was just a gremlin or it wont come back for a while.
