Hi all, I’ve got a 2012 Meg with the 1.5 dci 110 hp engine.

Recently, the car when left over night for example will be rough on idle when the car is started. You put your foot down and it’s misfiring in my opinion. Lumpy until the revs get to 1800-2000 then it smooths out.

I had left the car for a week recently, upon starting it, same roughness however the smoke was pretty blue. This only happens when the car is left for long periods.

I’m pretty handy with spanner’s and not worried about getting dirty.

The car is on 85k, recently serviced and EGR cleaned.
I wondered if it could be an injector issue but then would the problem be permanent instead of just the Lower Rev Range?

Any suggestions where to look next?
