Hi and thanks for using 2CarPros.com. Replacing spark plugs is not too hard to do. I will start with general directions first. Here is a link:

You did not mention if the engine is a 4 or 6 cylinder, so I have attached specific directions for both. I will begin with the 4 cylinder. Additionally, I've attached pictures that work directly with the directions.

REMOVE NO. 1 ENGINE COVER SUB-ASSEMBLY
To remove cover, Lift the rear of the engine cover to detach the cover from the 2 pins, and then lift the front of the engine cover to detach the cover from the pin and remove the engine cover. See pic 3 below.

REMOVE IGNITION COIL ASSEMBLY
(a) Disconnect the 4 ignition coil assembly connectors.
(b) Remove the 4 bolts and 4 ignition coil assemblies.

REMOVE SPARK PLUG
(a) Using a spark plug wrench, remove the 4 spark plugs.

Replacement is the reverse of removal.

For 6 cylinder engines, the air intake must be removed to access the spark plugs. This is a more difficult task. However, take your time and follow these directions.

REMOVE INTAKE AIR SURGE TANK ASSEMBLY

REMOVE NO. 1 SURGE TANK STAY
REMOVE IGNITION COIL ASSEMBLY
(a) Remove the nut.
(b) Disconnect the 2 harness clamps.
(c) Disconnect the 6 ignition coil connectors.
(d) Remove the 6 bolts and 6 ignition coils.

REMOVE SPARK PLUG
(a) Remove the 6 spark plugs.

As mentioned, this is more involved. Pictures 4 through 10 are related the 6 cylinder engine.

I hope this helps.

Cheers,
Joe
