    When setting your timing, be sure to disconnect the computer.

    On my '94 K1500, it was located behind the dash and underneath the glove box.

    I believe it is a brown or tan wire with a black stripe.

    Once it is disconnected, set the distributer timing at 0 degrees.

    Then after connecting the computer back up, the timing should readjust itself.

    Good luck...

    with the wire still connected your comp will go into default mode

    Clean your I.A.C as well..... That can cause a sputter...
