Road Test: Install a vacuum gauge in the manifold vacuum line. Perform a 10-12 inches manifold vacuum crowd in second and in third gear at
15-20 mph. If the manifold vacuum pulsates and the vehicle bucks or surges, the EGR valve is oscillating. Remove and replace the EGR valve
with a E2GZ- 9D448-J EGR valve. Retest to verify fix.
