the ECU can work fine when you unplug the O2 But when you turn the power off to the ECU it will reset that would be why it ran fine befor the O2 runs the fuel, spark,and timing the O2 has to be in, the speed sensor will not read right for it to send into the ECU make sure the cam gears are set at O"" befor you plug the O2 in and take off the + cable so it can reset. then start the Tune up.

I wonder if the timing is off on the cam shaft? If you are off one notch it could make it do something like this.

Mike, it sounds like it could be a vacuum leak. Check all you hoses and connections.
