air flow goes away with throttle

[russde]

OK guys, here's the situation:
Driving around town with the vent selector on 'vent' my air flow goes away when I get into the throttle any more than about 1/3. Is this normal?
It also happens when the A/C is on, but I know that some cars will do this in an effort to reduce parasitic drag from the compressor, so I assumed the SVO was designed the same way. But on VENT?

Sounds like you have a vaccum leak some where and the diverter door is closing on you.

The A/C blower fan is electric and will still operate when you punch it. However, the compressor drops out to prevent over pressurizing the A/C system during hard acceleration, but the blower fan should continue.

yea.. the ac compressor kicks out, cause at about 5500 rpm, they like to come apart

Sounds like you have some good advice from GAboySVO
