We have a microbore central heating system in the house. we had a problem with our overflow which was fixed but now there is lots of air in the system and the bottom rads and ones on the end of the system upstairs will sometimes only be warm or even cold. Any ideas what is wrong and how to fix it????

just for clarity I did not say that the OP Must powerflush I just suggested that they search for stuff to answer their question.
and powerflush and central heating cleansing would return some good posts

i agree leave our young un alone 
Powerflushing microbore is a big no no in my book..it doesnt work.
Thanks boys much appreciated, dont know where is has come from as up until recently me and lor got on ok?
I kind of agree with harrow, if the deposits are thick and hard powerflushing microbore is practically impossible.

Whilst power flushing on microbore is certainly more problematic, it is possible as long as there is some flow.
What you certainly need is one of the pump models ( or really "the only" ) which are capable of a high head over 1 Bar.
The other problem is that if the rads are sludged up and uses a double entry valve then each rad will have to be removed if its to be cleaned effectively.
