ok i have put on a new iacv and i still am throwing the code 14
i have checked vacume lines,cleaned the iacv, and checked the wiring, but i havent ran the wires straight to the ecu yet!!
the other thing that could be the prob is i have a dx tb on my z6.
i dont think the vacumme passeges line up right could this be the problem..
when i plug the top whole in the tb the idle will go down but you give it gas and it starts to stumble and,
this hole sucks air like a mother ******... so thats wats happening some one please help before i blow this bitch up...

 

bump it
