I cannot figure out why my idle keeps bouncing to the point where it bounces so low it stalls the car. I have installed a new ICV with new hoses on both ends, new crankshaft sensor, new throttle body gasket, new intake boot, new valve cover connector and hoses, and new MAF. Despite all the new items the car idle still bounces crazy to the point of stalling when it goes too low. Any ideas what else I should look at? Only codes that are being pulled are 1221 and 1215. I used carb cleaner to spray around for vacuum leaks around the manifold, but could not find any. The car's idle bounces exactly like this video: https://www.youtube.com/watch?v=B4YEZE1K_fg.

Is it during cold start, and / or does it continue when the car warms up?

Does not change behavior if car is warm or cold.
