speed but slow up

Check engine light? How did the gas pedal feel when accelerating? Did the engine rev to high rpms? How is the tranny fluid?

Its good i went and got an oil change so that all fluids can be checked but i was driving a little better but it did it again so i went and got a fuel injection and it was driving a little better it went to 55 i dont know cause it havent been driven in over a year and ya the light is on but when i took it to the auto store it said something about a leak

And when im trying to see what i could do on the high way i had to pull over but it pulled a crazy hill 3 times and changed out like it should have

Leak? Did the code say evap emission leak?

i had a similar problem and it turned out to be a slowly dying fuel pump, this was after a lousy mechanic and muffler shop said it was my cat converters, had them replaced but that did not fix the problem.
