Ford Diesel 2Ltr is hunting on startup ?

[DXP55]

Just a quick question.
My Focus is now 14 yrs old with 80k miles - Just recently on startup it sound like it's running on two cylinders then cut's in to 4 - After 30 sec or so and a few pumps of throttle it's fine and never faulters at any time - Gave it a Italian tuneup Sunday and did around 40 miles and tried to keep rev's up around 3k - I am sure it regenerated as temp was up to half way -normally it sits just under half - Why Ford didn't put a light on dash I don't know.

Has anyone any ideas.
I will probably find out next tuesday as it's booked in for MOT.

I gave it a Italian tune up last week -It's now intermittant so put some diesel additive in tank and later today off for a 60 mile thrash onto M54. Other than that it runs a treat and milage is 91k not 80k as in my original post.
Never touched EGR yet !

Ps. It regenerates but it doesn't have a Adblue tank.

Started well this morning and has survived a 46mile thrash and it never missed a beat - Wish bodywork was as good.

I think I will give it 80-20 it will pass MOT on Tuesday
