if you have an idle and stalling problem with a 3800 series 2, don't mess around with it.  change the upper and lower intake manifold gaskets, and the upper plastic intake manifold plenum itself.  and cross it off your list.  that problem will drive you f-ing nuts.  they can leak internally and defy all diagnostics.  the lower intake manifold can leak vacuum by pulling from the lifter valley area, under the manifold, from the engine internally.  IMPOSSIBLE to find with smoke, spray, etc.  just change it.  the gaskets are usually mush.

How do I find a vacuum leak? I'd highly prefer not to use a carb cleaner spray
I'm very new to xaml and I'm trying to understand the Binding issue. I have a problem with the Array Binding. I created this very simple example: I have a stack panel with three images. Each image has a RotationTransform. Each Angle is obtained by an array element (the array is a DependencyProperty called Rotations). This is the xaml simple file:

&lt;StackPanel Orientation="Vertical"&gt;
        &lt;Image Source="/Assets/knife.png" Width="50" Height="100" Stretch="Uniform" RenderTransformOrigin="0.5,0.5"&gt;
            &lt;Image.RenderTransform&gt;
                &lt;RotateTransform Angle="{Binding ElementName=pageRoot, Path=Rotations[0], Mode=OneWay}"/&gt;
            &lt;/Image.RenderTransform&gt;
        &lt;/Image&gt;

        &lt;Image Source="/Assets/fork.png" Width="50" Height="100" Stretch="Uniform" RenderTransformOrigin="0.5,0.5"&gt;
        &lt;Image.RenderTransform&gt;
            &lt;RotateTransform Angle="{Binding ElementName=pageRoot, Path=Rotations[1], Mode=OneWay}"/&gt;
        &lt;/Image.RenderTransform&gt;
        &lt;/Image&gt;

        &lt;Image Source="/Assets/spoon.png" Width="50" Height="100" Stretch="Uniform" RenderTransformOrigin="0.5,0.5"&gt;
            &lt;Image.RenderTransform&gt;
                &lt;RotateTransform Angle="{Binding ElementName=pageRoot, Path=Rotations[2], Mode=OneWay}"/&gt;
            &lt;/Image.RenderTransform&gt;
        &lt;/Image&gt;

        &lt;Button x:Name="actionButton" Content="Try Binding!" 
                Click="Op_Click"/&gt;            
    &lt;/StackPanel&gt;


And this is my c# class:

public sealed partial class MainPage : Page
    {        
        public static readonly DependencyProperty RotationsProperty = DependencyProperty.Register("Rotations", typeof(double[]), typeof(MainPage),
            new PropertyMetadata(new double[3]));

        public double[] Rotations
        {
            get { return (double[])GetValue(RotationsProperty); }
            set { SetValue(RotationsProperty, value); }
        }

        private void Op_Click(object sender, RoutedEventArgs e)
        {
            Rotations[0] = 180;
            Rotations[1] = 130;
            Rotations[2] = 350;
        }

        public MainPage()
        {
            this.InitializeComponent();
            Rotations[0] = 20;
            Rotations[1] = 90;
            Rotations[2] = 180;
        }
    }


The binding works only the first time (at startup time). When I click on the button (changing the Rotations array) the binding doesn't work and it is completely ignored from my images. 

This is a very simple example, so it's clear that I miss something concerning the Binding issue.
