Yes, all cars idle high when cold, it's all part of the emissions system.

Ok, thank you guys. Stupid question but Im young and couldn't find the answer anywhere. Is it easy to adjust the idle via the idle set screw on the TB?

Or is that best not to do?

Yes it was designed like that so that it won't stall.

There shouldn't be a idle set screw on the TB.

Won't really work. The throttle stop screw only sets the minimum amount of air (Minimum Air Rate) allowed past the throttle and it's usually something really low like 600 rpm. The ECM then uses the Idle Air Bypass Valve (IABV in Fordese) and Ignition Timing Advance to bring the idle speed up to what the software indicates it should be for the conditions present. In order to truly change idle speed and make it stick you would have to change the specified speed in the software. IE a tune.

can i do this with a bama programmer? also how

Why do you want it to idle lower? 400rpm isn't much especially that low.

NEVER touch the idle screw on throttle body with a motor/sensor
