I have a 98 CR-V with a JRSC and fuel management that I know needs to be changed (crome on the way) right now has FMU and VAFC2.

I recently changed out a bad PCV valve and I am not sure if this is a result of that or not, but the car stalls when you come to a stop. The RPM's drop real low and it just dies. Could this be something to do with the PCV swap, my Fuel setup, or something else like a sensor?

 

most likely fuel. my car did it from a faulty fuel filter.

 

when the car dies,does it the fuel pump pry right back up?

 

If you mean does the fuel pump fire right up..yes it does.

 

Check the fuel filter and since you stated you have a VAFC, if you haven't done so/tuned it yourself anyway check the fuel curves to see if it's trying to dump too much fuel into the motor at lower RPM's.
