A leaking manifold seal on the intake will cause a popping noise on the 1996 Honda Accord. This can heard most clearly on days when the weather is cold because the seals tend to shrink.
A leaking spark plug wire can cause a backfire out of the intake, but the most common cause is a burned intake valve. A burnt intake valve will allow leakage during the compression stroke back through the intake causing a popping backfire out of the intake manifold.
