I think this link below might help you based on your description of the problem.
Not sure where you put 12V onto the EGR valve though?
One other diagnostic will confirm the EGR ports plugged up;
Put vacum on the EGR while at idle, or reach your finger under the top and push it up, the engine SHOULD stumble or die, if not the EGR ports are plugged up.
