I have a 1997 Kia Sportage and I am having a problem. My car won't accelerate properly. It'll take up to 1 minute to get to 35 mph. I just replaced the fuel filter, and that didn't seem to be it. The oil change guys said that I really need a new AC belt. Could that be a contributing factor? I clearly know nothing about cars, please help me figure out what is going on. There are no free diagnostic places around here, they only do it free if you agree to fix the problem there. Anyway, it's a big problem. It scares me that my car will explode. It's been this way for a week or so.
