The wiring harness problem is caused by crumbling insulation. The insulation is made from a different formulation than usual, probably in the name of environmental friendliness. Heat and age cause the insulation the harden and crumble when moved. Shorts occur causing weird running problems. Replacement, or a diy rewiring, is the only solution. Replacement is not difficult, but you must plug the correct connector into the correct sensor or clip. Volvo tried this in the mid 80's and I had this problem on my old '86 740T. I bought a new harness and replaced it myself.
