the egr
the EGR modulator up on top of engine, uses CAT back pressure to regulate EGR flow
you ended that with rodding out of the cat.
just get the MAIN to close, and not leak
then defeat it with hose vacuum to it (rear valve removed and plugged)
in some cases the MOD can go nuts like this, (complex answer covered on the EGR MOD page)
so with carbon blockage now,is a blessing..
