Hey everyone, I've had my car at the dealership for 6 days now and just got it back today. It accelerates great in the city. I took it out on the highway and WOW nothing but disappointment, soooooo sluggish. The dealership replaced the "Inter rec air pump" and the "intake air temp sensor". Oh and they were kind enough to let take a KIA spetra as a loaner. What a winner. Any insight would be greatly appreciated. CYA
