alright heres the run down.. its a k20a3 and converted the head to a k20a2 by swapping out the rockers.. it runs fine except for at idle i loaded every possible map i can tried decreasing the fuel tables and everything no matter what i do my air fuel ratio at idle is anywhere between 10.3 and 10.6 according to my aem wideband which is brand new. i dont have a primary o2 or secondary they are both tuned out. it is a track car not beinig driven on the street also i am throwing a code p0563 vbu voltage high?? and have no idea what is causing it.. any help would be appreciated. ill put a datalog up in a litttle while at idle and when i give it a little gas idk what the problem is
