ok i have a 97 ls throttle body on my ls swap, and it doesnt have any vacum nipples? is this normal, my si engine had two on the throttle body. my swap idels like **** and has no power im thinking its because of the vacum lines also i have a MAP snsor on my fire wall, adn i also have one on top of the throttle body, which one should i use? i have a code 14 what is this? also what are the 2 vacum lines i NEED hooked up im not worried bout emmisions i just need it to run right.

thanks
