Bastero,
You are correct. After reading more I remembered that ICV was not making a sound when I was cleaning it. I took it out this morning and cleaned it better and now when I shake it hard it is making a sound.
After putting it back I noticed some improvements. Car doesn't shut down any more but is still jerking and every now and then makes that very laoud sound that I am pretty sure is the ICV.
Could it be that I need a new one?
