Im hoping someone in here can help me out a bit. I disconnected my exhaust valves, capped them with a screw in the line fist then had the "Air Flow disruption engine code bank 1 and 2" so i removed that an put actual silicon vacuum line caps on only the vacuum line. I erased the code and it came right back again. Does anyone have any suggestions? Do I need to cap noth inlet and outlet when disconnecting the valves? Anything would help as this has been an annoyance and I really don't want to bring it into the dealership.
