    95 VS Wagon. Exectutive.
    Speedo jumps up when you hit the accelarator in park.
    What would cause this?

    Shorting wires from the Revs to the speedo could cause this?

    **** design, the speedo is driven from the pcm, somewhere along the lines there's some interference in the computer, vr/vs do
    it and probably more, no fault and not much you can do about it

    my advice is to cut down on Speedo's red food colouring consumption
