Always remove the ignition coil assembly by grasping at the spark plug boot, turning the assembly 1/2 turn and pulling straight back in a steady motion.

1.Disconnect the negative battery cable.
2.Remove the intake manifold, (Refer to 09 - Engine/Manifolds/MANIFOLD, Intake - Removal) .
3.Prior to removing the ignition coils, spray compressed air around the coil area and spark plug to remove contaminates from around spark plug tube.

On 3.5L engines, it is necessary to loosen the screws by alternating back and forth. Do not lose the spacers under the coil when loosening the screws.

4.Remove the ignitions coil.
5.Remove the spark plug using a quality socket with a rubber or foam insert.
6.Inspect the spark plug condition.
