Sorry for the delay in responding. I just completed a 2,500 km road trip with the Aveo and I was not online very often.

Glad to say that everything went well and the CEL light stayed off. The mileage seemed pretty good too. Haven't crunched the final numbers, but it looked around 7.8 L/ 100 km.

Yes, the components were all replaced at around 91,000 km.
