I am assuming that the replacement engine ran fine for a while?
Did you disconnect the negative battery cable for at least 30 seconds and drive it for a while?
Any other codes?
What do the plugs look like? Is the spark fat and blue? Does the engine heat up properly? What fuel pressure?
Check the O2 sensor.
Good luck and let us know. :)
