    My first R12x did a similar thing. Ended up being dirty injectors. Using hose crimpers, gently squeeze the fuel return back to the tank and see if settles the problem down. If it does I would try and have your injectors cleaned.

    I would take it back to them and give them this 2 cents, that ecm can not be banging and bouncing around, sounds to me that they def. did not install it right and probobly DMG. it Most Honda Dealers dont even know how to do an oil change right and no saprise they did not sacure the new ecm right.
