Firstly I must say this a great resource to have on hand.
Anyway.. I have been having a few issues with my 86 325e in terms of shuddering and idle/surging problems. I finally found the shuddering which was in fact the right engine mount under the exhaust manifold had completely delaminated into two halves and the left one wasn't far befind in terms of damage. After a trip to Mr BMW parts and a $100 later she is shudder free.
Idle problems were fixed by removing my ICV and cleaning the sucker. I have read numerous faq's on the subject of which some say don't clean it and others recommend cleaning. Well after you would have seen what came out of the ICV its no wonder I had erratic idle. I connected the ICV to a 12v power supply in my workshop to check current draw which should be around 1.2amps when not connected to the ICM. Tests showed I had around 1.3amps and she was a little slow and sticky, so while powering the valve to hold it open I put a little carb cleaner in there and with some q tips I think thay are called in the US, I cleaned her out again and again. After each clean I switched the power off and on to the valve to get the grunge off of the main plunger contact face and cleaned it again with lots of carb cleaner spray to flush the debris out after which she now sits at 1.2amps.... My idle is now better than ever and is rock solid, yehaa.
I also have a surge at part throtlle which I am chasing.... but didn't notice it on the test drive after cleaning the ICV, which doesn't make sense at all.

Have you had the catalytic converter checked or replaced?
