I found this on a site may be the problem i don't know????

A common problem is the EGR valve sticking in the open position. This will cause excessive black smoke from the exhaust and will result in a lack of performance.

thanks for that where did u find that. performance is fine tho.

having the time to look at it is prob . will have to make some time doing my head in now

The lack of performance tends to be dependant on the presence and state of the DPF filter. Without a DPF you are more likely to keep the power as it is, however with one, if the thing is getting on a bit, you will find that it will be clogged, and that will reduce the power output, as it backlogs on the Turbo, and the exhaust...

Sorry for the delay in answering, I was researching my problem and I came across a focus known faults list but I didn't save it and now I can't find the site! 
