I'm stumped on 350 tbi motor

Motor ran awesome or so I was told before it was puled.. I can't get the damn thing to stop the slight rough idle.. It runs fine and smooth then gets a slight miss to it.. I've changed every sensor, tried timing it and still no luck ALSO I can get the fdamn thing to time to 0 with tan wire unplugged or it chugs then stalls.. If I leave it around 4-6 it seems to work great.. minor miss no and then, but as soon as shut the truck off, and plug the tan wire in, it runs good for 1 min then back to missing slightly and acting weird Any advice ?... thanx
