Need help with this vacuum reading

i believe you have timing issues or to much cam for the convertor /a big cam with lots of duration will = low vac readings

But wouldn't a wrong convertor cause problems when hot or cold? Would it cause it to die like this?

Keep in mind it also dies while just sitting in park.....let it sit idling and it will just keep getting rougher till it dies.

It doesnt die until its hot.....runs/drives ok to that point....
