How bad did i screw up???

Got to chime in here about some of these responses. I did the exact same thing that you did last year. I tried every trick including the extractor tool. Nothing would get that broken plug that was now still in the threads out. Spent a lot of time using every trick that someone suggested, and most were mentioned more than once, and they were good suggestions. However one person suggested something that nobody else did, and it worked. Take a soldering iron and after it heats up cut four lines, one on top, one on the bottom, and both sides and immediately after making your cuts, take a pair of needle nose plyers, and pull on a section that you just made with soldering iron. You may have to play with it for a while, but it will work. Do not use any kind of tool that will mess up your threads. Soldering iron will not damage your threads,and you only need to melt the plastic enough to pull it out. once you get one piece out the rest will follow.
