prognosis?

Frustrating. After replacing the injector, then replacing the plugs and wires, then replacing the cap and rotor, the thing still threw a midfire code for cylinder #5. The only other thing I could imagine was the injector electrical wiring so a volt meter was put on the injector electrical plug. The power to the injector is only 7 volts, but it was the same on all cylinders. I watched the VOM for a few minutes with the engine running and it never waivered. Then I started yanking on the injector electrical plug wires and it seemed to lose power for a monent. On closer inspection, the wire insulation seemed to have been crushed where it enters the plug. It was old damage - perhaps original. The insulation was stripped to find a couple of strands of the wire had been broken and the wire seemed loose inside the plug. I twisted the wire expecting it to break completely, but that seemed to tighten up the connection some so I just taped it up and put it back on the injector. It runs fine for the moment, but I won't believe it until it has had some miles on it. Has anyone ever had to replace an injector electrical wire? I suspect I'll have to buy the whole wiring harness if this band-aid doesn't work.
