Hi I have a 2006 Aveo ,standard. I hit the highway at 100km/ hour (60 in miles) then suddenly the car will slow down to 30 -40 and there is nothing I can do I hit the gas pedal and it won't go more than 30 or 20. I stop on the side of the road ,turn off my car wait 5 mins and start it up again. It will be fine for another 10-15 mins ride and it will do it again. It happened 5 times last night. I am being told it is the gas sensor.Has anyone had this problem. I would greatly appreciate the help pls.
