: Stalls after a fast stop

1995 BMW 525i Automatic

The car has 190,000 miles and idles perfectly. However, upon a quick stop (after the car has warmed up) the rpm's drop and the car occasionally stalls.

I have done the following maintenance to fix the problem a week ago:
New paper air filter
Oil change plus filter
New Bosch Spark plugs
Fuel Filter
Throttle body cleaning

After the general maintenance, the car is getting much better gas mileage, but the occasional stall on a hard stop is still there. There are no codes or CEL.

Any ideas. Transmission? Idle control valve (but idles great). Mass Air sensor?

Idle air control.

Is there a FAQ or picture(s) of how to remove and replace or remove and clean? All the old postings on the IAC have been taken down or are models that do not apply to the E34. I am figuring this is under the intake manifold. Have others experienced the same problem and solved this with cleaning or replacement?
