ok, engine runs like a champ after the swap except it has a bouncy idle. The idle operates normally until I touch the throttle, then it moves between 1200-1800 rpms.
Here's what I have done so far:

THERE ARE NO CHECK ENGINE LIGHTS
-Throttle body has been replaced
-Fast idle valve has been replaced
-Coolant system has been bled
-ALL vacuum hoses have been checked for leaks
-EGR system has been tested
-timing is dead on
-Idle control valve has been replaced
-throttle position sensor has been replaced
-Coolant temp sensor for idle control replaced
-Thermostat replaced
-Water pump replaced
-All wiring and vacuum lines have been verified
----------------------
When I lift up slightly on the EGR diaphram and let off the idle returns to normal, and then resumes bouncing as soon as the throttle is touched again.
Someone at a Honda dealer said that the EGR channel might need to be bored out, cleaned and replugged.
The engine is a Japanese import with very low miles. Other than the idle problem is runs great. I have also noticed that it DRINKS gas.

If you have any suggestions, PLEASE let me know. This problem is driving me crazy.
