I have a 1995 Mariner magnum efi 150 that has a lean sneeze/pop.. It runs absolutely perfect, but has this pop at idle. I have narrowed it down to one cylinder by removing plug wire while running. I have swapped plugs and wires to no avail. I sent the injectors out and had them cleaned. Still pops. Manual says reed valve..checked when I had the injectors out. None cracked or bent. Any help greatly appreciated.thx Marvin

Configuration (i.e., I4, v6?) and which cylinder - is it the bottom? or the top?
