EGR Flow
 

I have a 96 Explorer V8. The check engine light is on. I believe I need to clean a line leading to the EGR valve of carbon build up. Can anyone point me in the right direction as to how I can do this? Is this something I can do myself? I've already had the DPFE sensor and EGR valve replaced. This is my next step and I am trying to do it without breaking the bank...again.

Thanks
