I have 2012 dodge durango citadel 5.7 , just got a code about the throttle body being close so I decide to buy a new one and installed ,but when you push the gas it dosent have any power , and throttle body won't open when driving, any idea what could be the problem? Anyone . Thanks for the help .I'll appreciate.

 

Scanned for codes?

 

Yea but the scanner says no codes atm

 

the reason I changed the throttle is because I got a trouble code :throttle closed position performance ,we checked it without the air vent plastic and it never open when accelerating the car ,but now with the new one on it does the same thing.
