having an acceleration problem

[Stephen1124]

Ok so about 75-80% of the time i am driving up an incline (on a hwy for example) i cant accelerate even when the pedal is to the floor. As a matter of fact even with the pedal to the floor i some how seem to lose speed. can anyone tell me whats happening?

When was your last tune up (plugs, wires, cap, rotor, ignition timing)?

Any CEL codes?
