Ok, so you've ensured the EGR works (it opens when applied direct vacuum) and its passages are clean; so that exhaust passes from the exhaust manifold into the intake manifold. Now you need to make sure that vacuum actually gets to the EGR transducer valve, and that the EGR transducer valve is not plugged up. The transducer valve is located near the EGR valve; usually directly above or next to. If the entire EGR system is operational, you want to start looking into a possible lean fuel condition... perhaps a defective oxygen sensor. A fuel feedback test should be conducted, and we can only recommed a certified smog check repair station do this.
