Let me put it too you this way. After 40+ years of garage ownership the 0 RPM condition has to do with something in the clutch set up. Yes an EGR valve that needs cleaning has to do with erratic idle.
I would clean the EGR orfices as well as the throttle body. It too can cause erratic idle. Use a small tooth brush and carb cleaner in the throttlebody. The engine will idle a little rough after a start because of injecting the cleaner.
Once the erattic idle is stabilized and the RPM stills goes to 0 you have a clutch problem
Remember we are here to answer questions and we am not standing by your car to do a hands on diagnosis as we have to depend on what you write. There is no substitute for the sound and feel of an engine. That is 50% of the troubleshooting arena.
Good luck
