Hi, My Aveo is displaying this warning light. Not accelerating as it should, struggles to get up hills and can have foot flat on the floor and its still not going properly. Have noticed that when car is stationery, the revs are still going. Just had a new battery but still got the problem. Had the same problem 12 months ago and it just went away ! Weather here is just turning colder, don't know if thats anything to do with it.
