Still sputter sputin 1991 e32 735i with eml throttle body... strange idle

Sounds dreadful. My first thought was O2 sensor. But if it cycles up and down from cold, that can probably be ruled out. Stuck idle control valve or bad throttle position sensor (if it has one) would be my next guess. Lastly, the coolant for air temp sensors.

Throttle body with eml do not have idle control valve. Shogun says that the idle is control by the DME. I checked the throttle position sensor and it is smooth. Coolant sensor is within parameters and the air temp sensor came with the replacement afm. Need to double check the o2 sensor
