Car never use to do this, only recently, couple weeks, it has not been giving me the power it use to. Lower rpms the car sputters, acting like maybe fuel injectors not allowing enough gas when gas pedal is depressed quickly, but not to sure what could be the problem, the car is pretty old, and has had modifications done to it for racing, so I tend to do a lot, but since the problem havent done much of that. I run 103 octane fuel, could that be the problem. Thank you for any help and advice you can give
