Thanks for the reply Jim. Do I just have to clean the EGR valve?
Or, do I also have to clean the EGR passages under the brass plugs?
Also, if I have to clean the EGT passages, how do you take out the
plugs?? There is no way to grip them in order to take them out.
Seems like the only way to remove them is to drill them out. Am I
correct??

Thanks again!!!
