Hello,

Ok, on that year the Spider Assembly has been known to fail, and of course you have to replace the hole assembly. Pics of assembly below...

Ok, you stated that it "Did Bleed Down" if this is correct then you could have a leaky Injector.

When you changed the Plugs did you make note of what condition each plug was in. If still have plugs check out link below for spark conditions..... Scroll down the page....
