Ford Focus 1.6tdci - Diesel intermittent lack of power - focuskev

Have noticed on my 2005 Focus at 98000 miles that on start I get a bit of a rough idle and the revs sometimes drop to a point where its close to stalling. From the cold start and driving off Ive also noticed a power drop for a few seconds and it can be a bit sluggish when im on the accelerator. Have recently had a Maf sensor change(new one bought off ebay) and months back a DPF filter removal.

Does anyone know what this could be please?

Could be lots of things, the only way to find out is to have the fault codes read.

It has been chucking out white/ grey smoke until engine warms up. Ive put a bottle of diesel magic in the fuel tank thinking it may be blocked injectors but to no avail

Have a look at this thread on the 1.6Tdci. http://www.honestjohn.co.uk/forum/post/index.htm?t=91541

It could be that one or more of your injectors is leaking gas back into the head. Would be easy to check if you look inside the cam cover for any buildup of deposits.
