Might just need a new valvestem core... Go to a tire shop and ask if they can give you a "new" one (like from an old valve stem they've replaced) and if you can borrow the core installer tool (kinda looks like a screwdriver, works the same way). Did this all the time when I worked in a tire shop

If you mean the screwdriver/t-handle and plug system by "stranded", then they are actually quite safe, many tire shops use them, and I have plugged many (as in 100+) tires with them (and did one of my own last week
). They are generally sold as "temporary" fixes, probably for the simple reason that the average person doesn't know much about plugging tires
If the puncture is within an inch of the sidewall, or in the sidewall itself, the normal flexing of the tire will often cause a plug to leak. This applies to inside patches as well.
The problem with plugs is that many modern tires (especially low-profile tires) look fine on the outside when low pressure has caused them to actually melt down internally. The only way to be sure is to dismount the tire. Once you've gone to the trouble of taking a tire off the rim, you may as well spend 10 minutes boring out the puncture, cleaning the injury area, buffing it, applying cement, and then finally a patch/plug combo (one piece usually).
The problem with this method is that if the puncture is too big, the patch/plug won't work. Sometimes, if you do it right, 2 easy plugs will work... Sometimes, you buy a new tire
