abs ecu resistance across yellow and green is 97 Ohms

abs light is also on, I did not think that was relevant at first but maybe it is.
I was hopeful with crank sensor as plug crumbled in my hand truck side cleaned up okay but sensor side was junk, also sensor was covered with metal dust. Checking ohms as instructed above next.

Looking for help! This unit runs as a yard truck with PTO for auger/blend system. Normally runs at 1100rpms while pto is engaged. Problem is it will intermittently stumble/hiccup while running on the high idle, sometimes once or twice other times repeatedly. I cannot run this down the road to a dealer to get it plugged in and no one will come here due to age and software needs, internet etc. Any thoughts on what could be causing this? I have already replaced accelerator pedal with solved the problem of occasionally not staying on high idle, originally thought they were the same problem but apparently not! Appreciate any help...Thanks

UPDATE... Had a guy in truck holding the cruise control accel button and I started wiggling wires, when I got to the connector on the ECU idle ramped up and worked as it should. It is working right now I have product to blend on Monday I am curious to see if it will maintain the high idle throughout the process after that I will pull that connector and check for any corrosion.
Thanks to all for your input and help, everyday is a learning experience!
