Hi guys,

My 2.7L diesel 407 has been taking a while to start when turning the key and cranking over. But once it starts, it runs fine..... until this morning. It took longer than normal to start but then immediately ran rough. I gently revved it a few times, reversed it out of my driveway and then back into my driveway. It felt & sounded like it wasn't running on all cylinders.
I switched it off and quickly jumped in the wife's car because I was late for an appointment. Came back an hour later and it was fine again, took it for a spin around the block to make sure - all fine.
One or more of the injectors failing or clogged? Couldn't be a turbo hose leak because that would be consistent, surely? Any ideas or things I can test?
