Engine stalling when warm...

Hey guys,

When I get the engine to normal operating temperature, shut it off and then start it back up again within about 15-30 minutes, the engine hesitates and usually stalls. I have to give it a little gas and then it'll be okay in a minute or two. Ironically, it starts fine when cold, or after sitting for longer than a half hour.

Right now I have my idle air screw turned all the way in, because I was having some high idle problems. However, I made that adjustment months ago with no problems. By the way, anyone know why I'd need to have the IAS in all the way for the idle to be normal?

As always, any help is greatly appreciated. :)

You know, that could very well be... because I've also noticed that my air is not getting hot as quickly as usual. I'll check into it!

Other suggestions?

Sounds like you have a VAC leak, When the eng is cold you have an extra fuel injector that is making the mix much richer, when the car warms up this injector goes off.
If you have the idle screw turned in it indicates that the eng is getting all the air it needs for idle so it may be getting it from a leak or if the throttle valve is open a little it will be the same.
The large air hose connected to the throttle valve has ribs on it and it is some times hard to detect a crack that is a leak.
