In your case it very well may be the ECU. Try cleaning out ALL of the harness connectors behind the dash with electrical contact cleaner (Radio Shack carries it as well as most electronic supply shops). If the problem remains another ECU may indeed be in order. What are you driving? N/A or Turbo, Manual or Auto? I have another GE ECU which I know is good.
