It sounds to me like you have a vacuum leak somewhere. This is exactly what happens when you have a vacuum leak. First thing is to check all the hoses, especially the ones going to the ICV...second...did you replace the intake manifold gaskets? at 170k miles that's pretty much a must.

Welcome, as said check for vacuum leaks is the first port of call...

Welcome to the Werkz. Good luck with this issue. Are you sure you routed the vacuum lines to the correct connections?

Welcome to the Werkz! What you describe sounds an awful lot like a vacuum issue and unfortunately these cars rely heavily on their vacuum systems.

Welcome to Bimmerwerkz...... +1 vacuum, check that throttle body to air intake boot also, mine did crack when I removed my manifold in the M50 swap.

Vacuum leak.
You should check all of the hose connections you removed to make sure they are tight.
Your service engine light may also come on, to indicate you have a lean cylinder mixture, as air may be bypassng your mass air flow meter
If you have a leak at your manifold joint and you can't hear it or find it easily, you can take a can of starter fluid and spray where you think the leak is, you should hear a noticeable change in the idle speed.
