My Ride: AA SC 98 M3
e36 m3 idle, deceleration problems

I am trying to address an issue over on bimmerforums but am too new to link videos so I am going to post them here!

If anyone here can help please chime in!

My car is a 98 m3 with an Active Autowerkes Stg 2 kit.
10 lbs boost
m50 intake
underdrive pulley from 90,000 up to 98,000 rpm
supersprint exhaust
cat delete
m5 clutch
lightweight flywheel

Video 1 shows how car "hunts" for idle when warm and sometimes find it and sometimes stalls.

Video 2 show how the car is completely fine and runs great when cold.

Anyways the car has a real hard time "finding" idle when its warm, to the point it will sometimes stall out.

Also bucks when decelerating in gear, which also seems to be isolated to when its warm.

Its a new car to me, but obviously not new to bmw's but new also to fi.

Thought maybe icv but then why only when its warm? Maybe tune?

Also noticing a bit of oil looks sprayed under the intake area. Like its down in the area around the power steering resevoir and ontop on the control arm etc. Not sure if related but where is it coming from? Oil level is fine and all fluid levels seem ok.

Also vcg needs to be replaced, is it possible its getting oil into area described?

All I can think of at the moment. thank in advance
