Good morning,
The fist thing I would do is check the idle air control valve. it has a habit of sticking and the idle runs high. try removing the wire connector and see if the idle drops down to normal.

REMOVAL
- Disconnect electrical connector from air bypass valve assembly.
- Remove the two bypass valve retaining bolts.
- Remove air bypass valve and gasket.

What is the code number? I doubt it is the EGR valve at all but if you get me the code number, I can look at the flow chart for the code.
