A hunting idle can also be due to a work out air meter potentiometer. This is a pricey part and not readily available separate anymore. Try all the hoses and such first.

What about sensor wires (to the computer). Can those melt out and short intermittent sensors? Would an engine overheat generate enough heat to melt wires? If so what tapes can be used to tape it up and isolate the wires again? I can only think of heat shrink tubing but the problem is how to slip those onto the wire.?
