Car not excelerating

12-24-2007, 11:00 PM
My daughter just bought a 2002 kia rio Cinco. Of course everything was fine for 2 days then the problems started. It seems to have an exceleration problem. Won't go over 40 mph. Its an automatic and shifts in and out of gears with no problems, just won't excelerate. And it doesn't do it all the time. Her boyfriend seems to think its the tranny, but I was thinking more in the line of a fuel problem or clogged catalytic converter or something. Any thoughts on what it might be?

I would say clean the throttle body out first and check after that, if it is a clogged throttle body it will cause the Vehicle to not get enough gas to accelerate but could keep the car running if enough gas is getting in. Also a possible transmission problem, I had a 1995 Buick Century 2.8L V6, a transmission Ring broke in it which caused it not to go pass 60mph, Though you could tell because the Car would shake Violently. I would suggest taking it to a dealer and telling them your concerns about the vehicle.
