My 325i has surging idle, as usual I checked air leak, throttle switch under the throttle body, they are all good, then electrical test shows the ISV is out of spec. I have a new one in part bin, swap it in, all good.
The ISV that goes back are very new, about 2 years old. Am I just unlucky to have a bad one or it's the usual life span, it's a over US$200 part !!
