So we have had our 06 2.3L Wagon since December, and last month it devoloped a problem. It seems like whenever I get on the throttle hard, but not WOT it sometimes hesitates alittle bit around 40 K/PH and around 60 K/PH. Its usually around that and it seems like it is worse when I have more people in the car. It is of course under warrenty but the dealer over here couldnt find anything wrong. They said "Its normal for sport cars to do this" was there explaination....Any insight to this?
