90 Accord with lots of miles. By what I've read I have what appears to be a common problem, when at operating temp the car stutters at initial excelleration and fails emissions. It runs smooth when I disconnect the EGR. I have no codes and have replaced EGR, CVC, and EGR control solenoid. No different. I have read some threads that mention cleaning of brass ports but I don't see anything like that when I have the EGR off of the vehicle. Is this something that requires removing the intake manifold?? Is there anything else that it could be? Please help, I still have lots of time but little money left:)

Hrm, I think the 3G EFI EGR is different then the 4th gen. The 4th gen has a rail like a fuel rail excpet it flows the EGR gasses.

Could be lean misfire caused by vacuum leak.
