hey so I took my 89 gt to get smogged today, motor is all stock, has bbk catted H pipe.

these were my results, I have passed many times with two cat cars , this smog tech was bitching about the two cats however, but he said that's not the reason I failed.. he said my egr is not functionable? what does that mean?
and my timing is supposedly off? has anyone heard of this?

was hoping somebody can tell by my results what I needed to do? wanted to smog tomorrow if possible.

Thanks Ca Fords!!

Replace the egr valve clean the egr ports an should drop the nox.

The egr helps cool the cylinder temperature .

It's a vacuum connection.

I found mine when I did my engine swap, so it was after the fact.

9 out of 10 you fail for nox it's a egr problem.
