yeah, the Chevy mechanic has informed that this has been an issue with a number of Aveo users... had a sensor thoroughly cleaned; they used a spray can, which I think was made for cleaning brakes
@ petrified.rabbit:
not sure precisely what the "fuel rating" is but a number of gas stations I believe offer premium unleaded with techron usually at 95 octane rating, if that's what you mean... the car's 16v DOHC E-TECH II, multi-point injection, mileage is roughly 29500, compression ratio is 9.5:1...
Sure hope the problem won't return...
btw, the stalling happened especially if I immediately turn on the AC after starting the engine...
