Hi, people, glad to be on here amongst such knowledge on the Aveo's. My wife's Aveo dies at highway speeds, she pulls over and lets it sit for a minute or so and then it starts back up. It might go for a month or more before it does it again, but on 01-18-2012 it died 7 times. I took it to a dealer and had them scan it and all that showed was a 02 sensor problem. Could that be it? I put a can of injector cleaner in the gas on 01-20-2012 and it hasn't died yet......maybe a partially clogged injector? It is hard to tell if that is the problem since the problem is so intermittent. Please help while I still have hair............lol.
