Thanks for the quick replys guys.Yes when I put the new bosch stepper motor in I did adjust the throttle cable to take the slack out of it.

Yes the idle fault only happens after about 10 -15 minutes of driving and I think I know that air flap valve with the two rubber pipes running into the bottom of that big pastic air pipe from air filter to injector head.

for a matter of interest do you know which way the 2 rubber hoses go in that air hose hot cold flap valve??

I have it booked in next week to the local garage for them to change to inlet manifold gasket I bought from volvo so if the faults still there after that I will be stuck as I am running out of ideas on this problem
