the throttle body on a fuel injected engine has next to nothing to do with fuel. It adjusts air only.
if you're having fueling issues look else where.

if your idle is jumpy or too low check the IACV, located on the back of the IM.

Your throttle body does not control any kind of fuel. You have an electronic fuel injection vehicle...

well what you want to do is remove the throttle body completely and cap off the fuel return that way you get maximum air velocity and by capping off the fuel return it throw the perfect combo of air and fuel buddy
