Sometimes a car idles high because the mass airflow sensor doesnt work and then the throttle sensor assumes a default position of wide open. Maf, Map, and tps are connected.

To replace the power window motor:

1. Remove inside door panel, and locate the motor.

2 Unplug the motor, drill out the rivets that hold it in, then you can remove it.

3. the new motor may come with fasteners to install it, otherwise use 1/4 - 20 nuts and bolts to attach the new motor.

SOURCE: chevy astro van turns over but wont start when

Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,

It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump

SOURCE: 1993 Chevy Astro Mini Van not starting

if your mini van has a 4.3 litre engine v6, when you turn the key on you should be able to hear the electric fuel pump start. the fuel pump is inside the gas tank,if you hear the pump you might want to change the fuel filter. The thing about computerized engines and a throttlebody is that you need a fully charged battery to start work with.

SOURCE: Sticky throttle on 200 Chevy Astro

There was a recall on the throttle body blade on the 4.3 a few years back for the throttle body to stick in the close position. Yours being 9 years old makes me think that there not going to do anything for it but give you the solution to the sticky throttle blade.
The solution was to change the blade. You can try cleaning the throttle body blade by spraying throttle body cleaner in to the barrel of the throttle body. If you look down, you'll see the carbon build up and it may just need and good cleaning. 
If that does not work, you can buy a new Throttle body blade which is only held on by two screws on the throttle blade shaft.

Start with cleaning the blade and throttle body with throttle body cleaner. Just follow the instruction and you'll be fine. 
Keep me posted and good luck.

Where would I check for airfow and vacuum problems in a 1994 chevy Astor van.


Under throttle body. Take a can of carb cleaner(make sure you don't have plug wires breaking down) spray under throttle body if it changes the way the engine runs you found it. Egr and pcv are other less likely. Should be getting a lean code if you got a vacuum leak

1993 astro van wont start when van has been sitting for awhile. spray intake clean into throttle body and van starts and runs.


depends how long its been sitting if starts with easy start then its a fuel pump problem like the fuel has gone bad or the pump has gummed itself up ,so take it out and check that the pump still works as i suspect that its gummed up and good clean will cure it for you
