Do you have a CEL light on.Would be easier to check for codes Instead of guessing.Mind you Not all Inj problems will set the Light and Log a code.If you do pull the V/covers off check the Harness connection under the valvecover carefully at the Interior plug.You can run it with the covers off at Idle Oil spalsh is Minimal.Then Unclip the Wire to each Inj individually till you find the Miss,Also this could be related to A compression problem too Hopefully it is Just a Bad Inj for yor sake.You wont know till you find the Dead cyl and go from there..Just be sure theres Nothing that will get sucked into the Turbo intake while your running it.And be careful around Moving parts Like the Fan and such.Another way would be to start it up cold and Check each exhaust manifold port with your hand right after firing it up.If its a Dead hole obiviously it will be cold.They heat up fairly quick.Hope this helps.
