07 charger 5.7 Hemi ran perfectly with no codes until I Pulled out onto a highway and jumped on it for a 1/4 mile, got to the red light and it ran rough at idle but perfect at driving speeds at 1,00 RPMs it runs smooth anything lower it shakes.. getting a p0172 0175 code and a b0700 code. when it goes into closed loop and runs worse. changed injectors, plugs, map sensor, 02 sensors, cleaned throttle body checked fuses, no vacuum leaks I am totally lost
