Picked up my 110CDI last week and just noticed what seems to be a vacuum pipe disconnected off the top off the EGR itself. the pipe is there and connected to what I think is a solenoid?

I've connected back up and started the van and it is smoking a bit on tick over, just about to give it a run out and see if it clears up.

My question is should I leave it connected or disconnected and block both the end of the vac pipe and also the end on the EGR valve its self?

Also can doing anything with the EGR or this solenoid put it into limp mode with the dash light on before I try either solution?
