egr ? My 97 trans am threw a p0400 code ,when i was replacing the egr valvle i noticed the gasket covers two small holes on the valve but the new valve the gasket is punched for these two holes, is there a wrong or a right when it comes to these two holes,also after changing the egr it threw the code once more,i went out today and bought a solenoid but have not installed it yet.
