    Has anyone owning a pre 86 XN6 ever tried removing the
    whole Air Injection apparatus? ( I know it's probably
    illegal to do so) I noticed the 86 XN6 doesn't have one.
    Anybody know why? Was this a fix for the twitchy Idle
    syndrome? Every post-85 xn6 I've ever driven has a rock
    solid idle.

    Is the red and black delay valve in the WOT vacuum line
    easy to trouble shoot.
    The green electro valve is working and will fix the duty
    cycle at 35% when subjected to low vacuum but I put a
    vacuum gauge on the black side of the delay valve and it
    will hold a vacuum for alot longer than the 11 to 17
    seconds that the manual says is the delay time for WOT.
    any thoughts.
