Car acts like it doesn't want to go. Not sure if it's the throttle body itself or just the throttle sensor

Please have your codes read at a local auto parts store and post them here for further assistance.

Also please give more details about the problems.
Can you drive the car at all?
Does this happen when the engine is cold or at normal operational temperature?

To me it sounds like the car is in limp mode which will cause this problem, here is a guide to help you run the codes to see if any are stored.

this guide will give you more information on limp mode.

Here is how to change the throttle body out which should fix it. You might want to try cleaning it first sometimes that can help. Check out the images (below). Please let us know what happens.
