What is the firing order for the 5.4L, 1999?

 

1-3-7-2-6-5-4-8

 

Thanks man,
now another question how are the plugs numbered?
if I start from front to rear and starting from the passenger side?

{--------------engine---------------}
plug#? ---plug#?--- plug#? --- plug#? : this is the passenger side

plug#? ---plug#?--- plug#? --- plug#? : this is the driver side

thx

 

Passenger's side is 1-2-3-4, driver's side is 5-6-7-8.
