....reaching running temp the idle varies between 1400~1500 RPM. That's backwards from what it should be? I have replaced several hoses, checked all areas I could with spritzes of carb cleaner without any effect, so what other components regulate RPM at temperature? I'm no mechanic with the finer details of the D-jet system on my 1.7L motor.

not against 914sgofast2. I think it is the other way around. Maybe your AAR is stuck closed, during cold start the engine will run in lower rpm since no air coming In from AAR. and when the engine is on the proper temperature, rpm will go up. Maybe try to adjust ur idle between 800 and 900 when engine is already on the proper temp. But your cold start may need some acceleration since idle will be too low and If AAR does not get some air.
