Why would you need to remove it? Take your obd11 and put it up where you can see while you are working with ignition on. Then break that loctice loose and mess with the nut both ways until it starts to drop closer to mid 3s.
I think the loctite seized the nut to the bolt and you loosened the whole thing together. You need to tighten it back to where it was before than use pliers and a small crescent to adjust it
