I think new they are about $50 a piece now. I would soak them in a container of Techron Injector Cleaner for several days, shaking it once or twice a day. When you pull them out, insert the red hose from a can of brake cleaner in the open end, hold it tight and spray. It will help clean it out and show you what pattern you have. I've done this for several and it's worked great.
