Model year may help narrow down things.
Offhand, if I understand correctly - air comes out of the vents normally, except under heavy load / acceleration? If so, suggest you have a vacuum leak in the HVAC control lines somewhere. Finding it can be a chore - one of those handheld vacuum pumps can help divide and conquer the location of the leak - but still no fun.
Good luck, this is a tough time of the year for the A/C to not be going where it should - and keep us posted on what you find.
