Solve follow problem:
1.Stopped the surging that the motor was doing idling and also running down the road at a steady speed
2.Removed all of the surging and truck idles like new
3.Solved LLY Duramax surge problem
4.It is a direct fit for the LLY Duramax. It fixed the lopey/surging idle, the shuttering when coasting to a stop, and generally cleaned up how the truck runs
5.it fits all the lly motors. Be prepared when you go to change it out. Its a sob of a job. But it is better than paying a shop 1500+ to do it.

Install suggestion:
First try amsoil diesel injector clean.
A new fuel pressure regulator will fix the common surging and lopey idle that many high mileage Duramax owners have experienced. It is a good idea to replace the upper radiator pipe seal and also the y-bridge intake o-rings because both parts will need to be removed for installation purposes.
