if one plug goes black its not burning the fuel so id look for a spark problem to that cylinder.
(as long as compression is ok)is coil directly on top of plug or is there a ht lead. can you swap plug/lead with a different cylinder to see if the black plug fault moves to another cylinder

Have a look at the wiring loom fix at http://www.vectra-c.com/forum/showpost.php?p=862597&postcount=17 since it applies to a whole range of cars with Fiat Z19DT engines. The 3rd injector has a faulty connector. It only costs £12 for a new loom and it is easy to repair yourself. The link shows you step by step instructions. HTH.
