egr not working?

[quickbrick]

ive been messing with my egr for a while now. when i push up on the diaphram it doesnt stumble. i took a tube and attached it to it and sucked on it and it stays the same. i drive my car every day to work and back. i took the egr off and it had a little oil in it. i cleaned that out and put a new gasket on it. i took the doghouse off and cleaned out that port too. it still doesnt seem to work. the car passed emissions when i bought it. does this cause drivability problems? any other ideas? or is this not even worth messing with?

The passage way between the plenum and EGR port is probably plugged. Get some carb cleaner and air compressor and clean it out.
