Car stalls when MAF sensor is connected?

Many car models notice this problems.The Engine stalls with MAF sensor plugged in,but when MAF is unplugged,the engine runs smooth with check engine light on dash.

The problem you are discribing in most likely faulty MAFs.But if MAF is replaced with new and still same problem noticed,then  defect is most likely due to a failed PCM (computer) or the connection to it from the MAF to the PCM. That being said, in most cases when the engine runs ok with the MAF unplugged it normaly means the MAF is Bad.

This details will help.

Thanks.
