I'm 19 and trying and trying to fix my old gl-10. I'm am new to the forum and need some help. My wagon sat for about ten years outside and ran perfect when it was parked. Started up ran perfectly still, even with the old gas, pulled out in the street to wash and when I started back up it ran like crap. Acting like it had an intermittent cylinder. Real stuttery and idled on the verge of dying. So I checked to see if had spark air and fuel, spark and air was fine so we turns to fuel. Two injectors seemed like they weren't working and got change, change fuel pump and filter and of course the fuel. And it still is running poor. When driving the pedal will be to the floor and the car with speed up and all of a sudden fall on its face. Also will only reach about 40 mph. I have no idea how to fix it and need help. Thanks for your time.
