2003 nissan altima: 2.5l..the coil from cylinder 4..misfiring

Customer Question

where do you find the cylinder 4 on a 2003 nissan altima 2.5l? we're getting the po3o4 and our dealer told us to switch the coil from cylinder 4 to cylinder 3 and vise versa and we got the message that cylinder3 was misfiring then we'd know for sure it's the coil. But where are the cyliders and coils?
