I'm not gonna dignify all this petty bickering over terminolgy with a response, but I don't believe for a NY minute that the manifold heat valve is at the root of this condition.
In the opening post, the owner advised that:

Crank and it starts promptly but can't seem to sustain running. More cranking with too much "I want to run but I'm cold and going back to sleep!" Several more long sputtering spins and another cylinder comes online...
The cold hard facts are that the exhaust manifold cannot make enough heat in such short time to have a significant impact on running so soon after a cold start.
THE PROBLEM IS WITH FUEL DELIVERY AND/OR IGNITION TIMING.
Use of starting fluid is nothing more than a band-aid - and a potentially dangerous one at that. Sure, that stuff makes cranking a lot easier - after it washes the oil off the cylinder walls, thus lowering compression. Guess where the rest of the fluid goes after it has compromised the seal between piston rings and cylinder? Keep on squirting enough of that stuff down the intake and you might get to see, first-hand, what a piston looks like with the top blown out of it - or worse.
I've only ever used starting fluid as a last resort, but I have never had to use it to get an engine running, no matter how long it sat, UNLESS there was a problem with FUEL DELIVERY AND/OR IGNITION TIMING. In fact, I have started more than one of my daily drivers, with a stone cold engine, in subzero weather and gotten them running - and more than once - here in Pennsyltucky, without a single drop of that stuff.
The real problem with this vehicle could be diagnosed in minutes with the laying-on of competent hands. It ain't rocket science.
