its not the ECU, no doubt it was some complete idiot as usual that told you that.
ECU's don't just break, or decided to break now and then.
you need to give more info on the problem as you haven't given us much. |

well ignition is not a problem. I would go with lambda sensor or coolant temp sender fault.
How does it start from cold? And if it starts ok when cold does it run ok before its heated up? |

lambda will make the car surge under any sort of light loading. But themn again when the cars heated up thats only when the lambda sensor is aknowledged by the ECU. Unplug it and see how it goes when it next plays up.
it could be many things, CTS even crank angle sensor, also make sure the TPS connector is fully clicked home on the throttle body. |

also make sure the map sensor pipe is ok and its connector is fully home and on the TPS make sure the arm isn't jammed at full throttle position like JB's was. |
