The EGR code can pop up for other reasons ! running rich (excess fuel) running lean (not enough fuel) ..Missfire causing excess fuel not burning during combustion .. the CKP(crankshaft position sensor) controls spark and fuel timing .. so remove and clean this first .. then remove and clean the MAF(mass airflow sensor) this controls fuel/air mixture ... be very carefull cleaning the MAF it is delicate inside ! use a MAF cleaner from an autoparts store !!
Hope this helps
