Thanks again for the help.

the EGR puts gasses from the exhaust into the motor to be recombusted. this cleans up emissions and cools the chambers.

quick test: pull a vac line off of something unimportant (i.e. dont use the line to the FPR). put it on the EGR with the motor running at idle. the idle should degrade once you apply the vac line. the valve is ok if the idle degrades. that leaves the solenoid, vac line to the EGR, etc.
if the idle does not change, that suggests the valve is bad or the ports are clogged. (the ports being clogged is highly unlikely).
