I was going 70 mph on the highway turned on my exit and started acting like it ran out of gas, it stalled and i started it back up and it wouldnt accelerate and the rpms wouldnt go up and if i put my foot on the gas too far and let go it would stall, rpms never went past 750, it idles at 500 rpm now, it wont go, never had problems before, its a 1995 S Galant Manual, it starts but only when i put the gas to the floor, i checked the fuel filter its fine, i checked if the fuel pump wasnt working its fine. it runs but doesnt drive.
