i have a 93 geo prism. when i start the car it runs fine. the problem lies in when i drive the car and when i get over 25 mph the car splutters and dies. or reving the motor at high rpm. is this not enough fuel pressure to the engine? should i replace the fuel filter 1st?

Optional Information:
1993 Chevrolet prism 1.8litre
