Sounds like a load of Bull---t to me.  Did your mechanic trace the Oxygen 
sensor outout all the way back to the computer?  If you are not getting 
any output (0 voltage) from the EGO to the computer, it will result in an 
always lean code.  A bad EGO may cause this, or faulty wiring.  This 
would be much more likely than the ECU going bad.
