I know for certain there are no leaks within the engine bay including the two short hoses just beneath the filter. It definitely runs rich though. It was pretty bad for awhile and was fouling my plugs. Since replacing the bosch 13091 oxygen sensors with oem I haven't had any more fouled plugs but my z still struggles to maintain a 14.7:1 ratio at idle. Usually closer to 12 or 13:1. If you let it idle for a couple minutes it will sometimes eventually wander back to 14.7:1.
