After reading through the forums I decided to clean the ICV. While working my way in I discovered the internal vane/flapper of the 'intake manifold runner valve' (realoem part# 11617544805) was broken at the actuator connection point. Does anyone know what this part is supposed to do? Could it cause rough idle? I ordered a new part and it hasn't arrived yet. I'll let you know what happens after I replace it but I'm interested in your opinions. Thanks
