I was having an problem with my EGR.. But I did what someone told me and all it good currently! I just sprayed the heck outta the EGR with carb cleaner and took a few Q-Tips and cleaned her out and it seemed not to work on the first run, but after a few mins a start and go, it came back to life and works fine for now.
So Clean it with some carb cleaner and grab some Q-tips and a few shop rags and go to town!!!
