Been a while since I cleaned the IAC on my 1991 745T, but the little door in there **IS** supposed to move if I push gently on it with a screwdriver, isn't it?
If the answer is "yes," then I think I have found the problems with the idle surging and poor driving.
I'm pretty sure that the little door, which operates like a revolving door, did move the last time I cleaned it. It is frozen in place now.
Now, if someone in town has one in stock and will charge me an arm and a leg for one. Heck, if the price is right, I'll even consider buying it from Volvo.
