Thanks for the reply and the guess, coil packs will set a different set of codes however yes i swap them from my other bmw with same results.
im waiting for the weekend to swap the throttle body and check.
my other guess is that since it is unmetered air codes, maybe the valvetronic is acting erratic changing valve opening and causing the unmetered air. and last wiring, i checked already and it checked out ok but who knows. something shady is going on in there.
