I'm KAT, or was till I tossed a rod. Now I'm a lowly NA 240 again. Regardless, point is I kept my EGR system intact. The only thing I modified at all was the PCV system. If you disable the egr system you'll need to have a capacitor installed inline between one of the plugs and the ecu to prevent this same light from coming back.
Also, you can try removing that valve, cleaning it and putting it back on. Or run some seafoam through the whole intake.
