Hi there,

This code is usually the result of a plugged up EGR port. Try cleaning them out and make sure the egr valve makes a difference in the way the engine is running. If you push up from the bottom of the egr it should cause the engine to stall. If not, then you have plugged port or a faulty egr valve.
