Massive airflow

What is your question?

Replaced the MAF with a used one. When driving it is ok but when sprinter is stopped a white cloud of smoke comes from behind. Does it need to be reprogrammed in the computer or not? When I unplug the MAF from computer no more smoke. What is the reason?

What makes this problem better or worse?

When MAF is plugged into the computer is when big cloud of white smoke happens

How long has your 2007 Dodge Sprinter 2500 had this problem?
