quick header EGR port question

[Fresco]

well my OBX header has a crack at the EGR port and is giving me the p0171 code, now my question is this, if i completely block off the port after i get the crack welded and leave the EGR tube disconnected will this cause another check engine light, or will it be fine?

you will get another light. get the crack fixed, and reconnect the tube.

You could block the fitting on the header and put a breather filter on the egr If you wanted to, no code should get thrown
