I have a 07 T800 that I run a rolloff trailer with. I use the high idle constantly to speed up the hydro pump. Lately the high idle turns off on its own for no reason. Sometimes the high idle cuts out many times while I’m running the hydros. Can’t figure it out. The cruse control has never acted up while driving down the road. Just the high idle. I’m lost and looking for suggestions. Thanks in advance!!
