What is the problem when the oil gauge on a 2000 Astro fluctuates as you accelerate and decelerate?

How much does it fluctuate? It is normal for oil pressure to rise maybe 20 pounds when you rev the engine. My SUV goes from 40 pounds to 60 pounds and then back down to 40 at idle. this is normal. The faster the engine rotates the more oil pressure is needed to keep everything lubricated properly.

2002 Astro van has recently decided to start blowing the air designated to go to vent down to the floor.?
My Astro van has recently decided to start blowing the air designated to go to vent, down to the floor. It I tell it to direct to defrost, it does. When I start in the morning, it will blow at my feet for about 1 mile then go to vent. If I start it from cold in the heat of the day, it will take 8 or so miles to assign it to the vents instead of the floor. If I go up a hill or accelerate quickly, it will go to floor and then back to vent when I go downhill or decelerate. Anyone familiar with this? Do you think its the 1/8 inch vacuum line that runs from the front of the block to the back? If this was bad wouldn't it do it all the time and not just at these times?
