What would cause erratic icp?

[MadDiesel73]

I was out listening to my stereo system pretty loud with the truck running (2500 watts) The lights were dimming and started idling rough, I shut it off and went inside Now I have erratic icp and idle. My icp will jump from 500-2000 at idle and 500-900 rpm. Truck/icp runs fine except at idle.

unplug your icp sensor and see what it does first of all.

Wire rubed on the lift bracket..

ICP sensor could be leaking oil in to the connector.
