I cleared the clogged EGR valve body and intake manifold port
and the oil separator. After reassembly with new gaskets,
the engine is idling nasty rough, and the ABS light is on an off with the brakes funky as if I'm losing vacuum. I think all the vaccuum lines are OK but maybe
I missed something.

Strange that the brakes are really bad then fine. Is that a feature of
an intermittant vacuum leak? Can the EGR valve cause this?

It threw codes A2- 154 231 232
EGR flow too high,
Long term fuel trim at limits at idle and partial throttle
Is there some adjustment upset with the throttle components?
