Right so I cleaned the electrical connectors to the injectors and found one broken and one will a seal broken sp they'll need replacing. Also bland of the egr because when I sucked on the vac pipe nothing happened, this worked for a couple minutes then it started running rough again.

Checked fuel lines but it was too dark by then, when I lifted the black rubber cover under the rear seat I notices it didn't sit right, it stand of diesel and everything is right up against the whole so you can't get to anything, is this normal???
