ok guys i noticed my car vibrating like crazy at stop lights...first i thought it was a dp rubbing issue....but no i watched today and everytime im slowing down as im almost stoppped my rpms dip down to about 450 and they keep dipping slightly at the light from 850-650 and the dipping is causing the vibration almost like it keeps coming close to a stall....what would cause this i know i got a vacuum leak because my ltft's are +16.4 any ideas if i brake torque and raise the idle myself the vibrations go away...so i wanna fix it lemme know...
