3 Extras. 1 of them was used on a MKIV supra from the guy I got them from so I've seen it work personally, and the other 2 were just aquired as spares and said to work. I noticed your situation, if you don't know how to test yours or think its bad, I can send you one for free and if it solves the problem you can pay for it, if not send it back. Just throwing that out there..
