    ya you have to live with idle set at 5-6 ,try side gap plug (j-gap)seems to idle little better-allso down the road have someone check throttle body settings with lap top OR check on line manual there's a setup voltage,just set to high side of spec.
    but who idles? you could ask wfo (rich ) he better at this stuff or if kenndy on line ask him(he's mess with that stuff more than I) BUT get that tach. need rpm #.
    O yes what year?

    green - idle
    yellow - midrange or addtional fuel when you pull the throttle. It will come on as soon as you give gas along with the green light. They both should be on when you give it gas.
    red - high speed
    and the last one at the bottom is for when you want the high speed to come on.
    I've had mine set at 3, 3, 1, 7. Set the idle up first (green light). Basically give it enough fuel/take away so that your idle rpms are around 1250 to 1300. Then when you pull the throttle, if it bogs, try and richen up the yellow light. See if that takes the bog out. If you richen it up and it gets worse, take some fuel away and see if it clears it up. Hope this helps.
