I was told by a really good friend of mine{ who is also a Honda mechanic} to remove the neg. battery cable for a few minutes then reconnect it. To my amazement that seemed to help the problem. He said it reset the computer.

Yep. As RedRide added, it resets the ECU (for some reason your mechanic didn't use that term). After replacing my battery, my Yaris was running a bit rough. CTScott replied to give it a few more miles, that the ECU needed to relearn the fuel trims. CT was right, later that day my Yaris was running just fine.
