The cold start valve has NOTHING to do with the CHT sensor. If the CSV is constantly energized, there's a fault in the wiring from the starter through the thermo time switch. If that were the case, your starter would likely be continuously engaged, as well. If the CSV wire is unplugged and it still leaks, the valve is bad. Rare almost to the point of "never happens". If you have bad trigger points, by far the majority of the time the affected pair of injectors won't fire at all, rather than firing too often, but I suppose it "could" happen. Bad grounds also mean the affected pair of injectors won't fire at all. BTW, the location of the injector wires doesn't mean very much, because each injector fires twice per cycle. The CHT, the MPS, and a leaking CSV all affect the whole engine rather than a pair of cylinders, and it seems to me that you may have other (mechanical) issues. I'd adjust the valves, look at the movement of the rockers, and do a compression test before I went any farther. Both affected cylinders share the same cam lobes.
