If I unplug the eltrical wires into the icm plug them back in the car starts and its been cuting out idles high sometimes if I unplug throtale postion senser it idales down and smoths out plug back in runs fine it can last mints or days don't know what to do with it

This could be a pcm issue, try tapping the pcm when this occurs see what happens, also look for corroded conections at the pcm.

I trade taping the pcm and check all wire conters. The will run for minets some time days befor losing spark when it loses spark the icm never loses power to it. It cranks over for a while before it starts
