Several answers could be given here, check all your vaccum lines for breaks or cracks. Check your EGR valve on this year as its electric and has pindle that opens and closes at its necessary time and can get stuck if its carboned up from the engine fouling. You can remove the two 10mm bolts and clean out the unit with carb cleaner and also the intake with carb cleaner and let dry. Check the pindle for movement(pindle it the little button object below the open hole above). If stuck clean and let dry and re-assemble, if gasket is old and brittle, replace or vaccum leak can occurr. Also, poor pressure form the fuel pump, could be dropping pressure during prior to the regulator.
