Today I went to work on my Z for a little bit when I got home. I decided to start it up to determine what I should work on next and like always, it turned over, idled at 500rpm then stalled... but I started it a second time and it sprung alive like there was never a problem with it. It idles great and revs up like a champ! I have no idea what happend, it was like it came out of a coma unharmed. I would like to thank everyone for the suggestions and help that got my Z back to how it should've been all along
