help!!!!

I have a 2001 ford explorer xlt. if you push the gas pedal all the way it will go really slow until it reaches 25 mph then it just takes off

If you ease into the accelerator gently, does it accelerate smoothly, or still seem to bog?

I try too explain a little better. it does do the same thing when you accelerate slowly and i should say that it only does this sometimes. also sometimes when your stopped when you start going it feels like the front of the car is shaking.

one more thing sometime when your going 30 and you try to speed up to around 40-55 it does the same thing where it won't accelerate almost at all

Sounds like your Explorer is in need of a tune up, and have the vacuum lines looked over. You may be experiencing a misfire under load due to worn spark plugs, arcing spark plug wires, restricted fuel filter, weak fuel pump, dirty fuel injectors, restricted air filter, etc.

As part of a tune up, I would expect the plugs to be checked and or replaced, the plug wires to be inspected and/or replaced, the fuel filter to be changed, and a bottle of fuel injector cleaner added to the fuel tank. The air filter should also be inspected and probably replaced. This seems like a good place to start based on your descriptions.

Other items to check: coolant temperature sensor, oxygen sensors, fuel pressure, mass airflow sensor, throttle position sensor, EGR valve.
