i have an o6 mustang gt. i recently installed a new steeda cold air intake, flashed it with the sctsf3 tuner, and installed a twin BBK 62mm throttle body. i custom ordered a tune with a trained proffesional so i doubt it is computer problems, however i am not throwing away the fact that it could indeed be a comp prob. the problem is when i start the engine everything is fine, but once it starts to idle, it hovers around 1k rpms and stutters likes its just on the verge of dying, but never quite does die. i press the accelerator but i dont get any response. i have taken the TB on and off several times and switched beck to the stock throttle body several times but to no avail. i have quadruple checked all hoses and wires and cross referenced them with the manual so i know where they belong. any advice or input to help solve this problem would be appreciated.
