Well good to hear you got back up and running , yes I would think with your lower vacuum, is giving your braking issues , is it possible for dizzy to be out one cog? if it dropped right into place after you changed out intake then I would think not

The ports believed by one fellow board member is one for gage the other for temp light as different gage packages used either side for sensor ,7 hole gage package drivers side , 3 hole gage package idiot light passenger side
