I discovered a section of the engine wiring harness which was expesed and was chaffing... several wires are corroded in that harness, another part of the harness horizontal with the road had a entrapped a pool of coolant. I checked all the splices and connections for corrosion, all is good. I`m sure I found another problem or hopefully the cause of this problem. On the top of the transmission, next to some linkages, I think is a module that is a smile for 20Pin connectors.the Socket on the module, (that the connector connects to) Cracked right off the module. I will look closer. I remember In the service literature, when the coolant temp gauge is at 260, look for a short or an open at C100, and this module is the next thing connected to it.
Its a large connector and its the first obvious problem I found so far.
Also the straps that hold down the Crankshaft position sensor wire away from the exhaust crossover, let go. It was not accessible enough form see any check it for heat damage. Wire loom for cps is brittle.
I already fixed the intake tube crack, all the hoses that had damage I fixed with good epoxy.
I now have a right turn indicator light partially lit on my instrument cluster
