on the old obd 1 system, there is a position sensor on top of the egr was a common failure. the egr pindle gets worn over the years and does not seat anymore, no matter what cleaning you perform.
as my 2 comrads said, get it checked but i bet you end up replacing the valve with the sensor.

Likely has internal pintle stuck open. Remove egr and replace as needed. May find lots of soot buildup. Can get egr cleaner at the parts store. Replace gasket when do it.
