So I have tried to do a little research and have not found much. Recently I noticed on my 2001 GT with a vortech V3 my afr used to be 11.5-11.7. However recently my afr dropped to low 10's. I really did not change anything. I did take off my discharge tube and changes the iat sensor about 12 inches closer to the throttle body. But would that really affect everything like that? I replaced everything and it is all tight. I have no other ideas for what it could be. COP? Bad plug? Would that cause my wideband to read rich? Any help would be appreciated! Also no codes have been thrown yet.
