THE SPARK PLUS ARE LOCATED UNDER THE VALVE COVERS, ON TOP OF THE VALVE COVERS THERE IS A SMALL PLATE COVER WITH 8 LITTLE BOLTS THAT NEEDS TO BE REMOVED WHICH WILL THEN SHOW YOUR COILS, UNPLUG COILS PULL COIL OUT AND SPARK PLUG WILL BE LOCATED UNDER THE COILS.
The left side is easy, just pop off the left side engine cover...remove the coils and the plugs are right there. The right side is a whole other matter completely, you need to remove the intake manifold to be to access them. It is a relatively simple job if you are even slightly mechanically inclined. Ensure you replace the upper intake manifold gaskets when you remove the intake manifold.

You can check the input voltage at each coil. This way you make sure you have the proper amount to operate. Disconnect the six ignition coil connections. Turn the ignition key on. Check the voltage at Cyl #1 B/Y wire, Cyl#2 B/U wire,Cyl #3 B/O, Cyl#4 B/G, Cyl#5 B/R, Cyl#6 B/W and ground. It should be 10.5V or higher. If not,you need to find the cause of the voltage drop.
If ok, you can test the resistance of each coil. At the coil,measure the resistance across the primary windings.It should measure between 0.50 Ohms ans 1.00 Ohms.
I hope this information is helpful.If you need anything else,don't hesitate to ask. Thanks,Chuck.
