I own a 95 Dodge Dakota with 77,000 miles on it, but for some reason it doesn't appear to be pulling well. I had tune-up done. I am not sure what's causing the problem. When I step on the accelerator pedal, the vehicle does not respond with the amount of pulling power that it should. I have not yet checked my fuel injector/filter/pump. Any ideas anybody?

Thanks
