Idle Speed and CO adjustment. 700 1987

I have an 85 740gle nonturbo. I recently cleaned my throttle body and followed the FAQs. First reading of RPM was 900. I ask about the wires, mine are like yours. Someone posted here to short/ground out the white/red. I did, and nothing changed. I could get down to 700RPM, but that was with the adjustment screw turned all the way in. It didnt make sense to me, so looked at my Haynes manual, its specs showed 900 for mine. Grounding the wire didnt do anything. So left it at 900. Can't give you a C0 comment, no testing in this state.
