Try to get the codes with the paperclip test, if this engine has an egr clean it out, or blank it off.
Did you clean the replacement icv valve, there are how tos on all the above on here. Could be the map as suggested, afm could also be at fault, there are so many issues that can give such problems, it is a matter of trying and discarding until you get the answer you are looking for.
Could also be that the injectors are at fault, put some redex in the tank, and see what happens. Sorry, there is no definitive answer that I can give, but do try all the above. I know what you mean it can really p*ss you off at times, but keep working away and you will get there.
There is also a great wee post on here I think, it is called all you need to know about sensors. If you cannot find it, let me know any old email address you have and I will attach it for you, it is a real help beleive me.
