What is the sequential order for replacing the # 4 spark plug 2008 4cyl? on 2008 Chevrolet HHR

The scanner code indicates that the #4 spark plug is misfiring. I would like to know where #4 is located using a diagram if possible. Thank You

Number 4 is at the rear of the engine. Rear of the engine is on the drivers side! Front of the engine to the rear it is 1-2-3-4. Front of the engine is on the passenger side where the belt is.
