Apply vacuum with a mighty vac pump, (hand held vac pump) and make sure that the new valve is actually working, it may be stuck.

You will also need to check the manifold vacuum at the port that hooks to the egr valve preferably. You should have about 15 inches of vacuum at base idle. If you don't, look for vacuum leaks and also consider that a plugged exhaust, i.E. A failed catalytic converter can cause low engine vacuum

Have you tested ported vacuum for the EGR valve? You can get cheap vacuum test gages from most parts stores.
