    Dash Lights

    Ok so my dash lights have not worked since I got the car. I looked through some wiring diagrams on all data and Mitchell and it shows that it runs through a printed circuit. How can I fix this?

    I forgot to mention that there is no power even reaching the fuse block

    If you have no power reaching the fuse block, you have more circuits dead than just the dash lights.

    That totally depends on lots of stuff: cam timing (mostly intake valve closing point), valve size, idle speed, static CR, amount of intake side air leaks, altitude, temperature. timing, etc.

    Stock 85 engines show 15-17 In Hg. idling, warm. Slightly lower for an 86. Most cammed engines show about 10. Retarding base timing usually lowers idle vacuum while advancing it usually raises it (slightly). A sooner intake valve closing point will increase vacuum levels. A higher idle speed will also increase vacuum levels.
