First check if your throttle cable isn't tightened too much =)

Maybe disconnect your cruise control cable and see if that fixes it.

Otherwise, check your ICV.

Where is the cable? I'm new

There's two steel braided cables going to the lever on the throttle body that controls the butterfly valve. One is from your accelerator pedal, the other is from the cruise control unit. You can figure out which one is the cruise control cable because you can trace it to it - the cruise control is by the passenger side front fender. The reason I said you could try disconnecting it is in case your cruise control is acting up and opening your throttle. To disconnect the cable, you want to do it at the throttle body side, it's basically a plastic clip that you pinch with your fingers to get it out of the metal lever.
