Is it my thermostat or heater control valve? Or is it something else?

Air in the heater core jack up the front of the car higher than the heater and keep adding coolant until the heater heats up. Then buy a new radatior cap and keep coolant in the resv. to prevent air entering in the system. You can just remove one of the heater hoses the top one and fill until coolant flows out of both hoses and place the hose back on. Hear any gurgling behind the glove box on start up when you rev up the motor?

Coolant level is a possibility, but if you are not having overheating problems, I would be skeptical of that. But definitely check it.
More than likely it is a vacuum leak.
There is a little door that controls the amount of cold air mixed with the warm air. The position of that door is probably controlled by a vacuum motor. When you accelerate, you produce more vacuum and so the door is held in the correct position.
Just a theory, but I have seen this sort of thing before.
Good luck

Low water, and- or undesirable rigidity cap, -- now and returned you may bleed some heater structures,--yet on account which you pronounced that it does blow heat air now and returned, that for the period of all probability is okay! without rigidity, the water won't "not sleep" in heater center! my own vehicle does the alternative, in spite of the shown fact that that's by way of fact it has a "quite often plugged" heater center, and that's "like taking your tounsils out through your ear" to get it out! So we live with it till in summer a minimum of! you may verify and notice that the vaccuum equipment (for heater) isn't leaking - or administration valve undesirable too (unlikely yet available)!

Your heater control seems to be the problem. Accelerating , low vacuum, it stays to heat.

might be low on anti-freeze, or bad thermostat. My car used to do it, because i had no thermostat in it. Which is the same result as the thermostat sticking open.

Check your coolant level, if it's low water, won't circulate through it at idle.
