In most cases, if the EGR ports are clear, then it is the DPFE (EGR SENSOR) sensor.

It is on the backside of the intake manifold. It will have a vacum canister mounted on an aluminum piece. My '98 4.6 had the same code and both EGR ports were plugged with carbon. Cleaned them out and reset the CEL.

Get a Chilton book at the parts store, not the Haynes.
