i have recently replaced my throttle body with a used one bc a new one was 900, not sure if the used one messed up but my car started to die on the freeway and when i let off my pedal and accelerated it started to run again but then gradually started to die on me i finally pulled over and it wont start now any suggestions.

 

Possibly throttle position sensor. Just my 2c

 

Thanks i was kinda thinking that may be it
