i bailed on this effort.
EGR tube was pretty clogged, cleaned as best i could & reinstalled a few minutes ago.
should the passage be oily? when i removed the block-off plates, they were both oily.
time will tell if its fixed.
anyone want a set of block-off plates?

 

Im sorry it didnt work out for you. I removed the entire system minus sensor and have not had one code at all other than an o2 code which is obviously not related. I dont understand.

 

no biggie. took longer to clean out than install
