2003 Ford Taurus spark plug diagram

Could someone please provide a spark plug diagram for a V6, 3.0L, 2003 Ford Taurus? My 4th cylinder seems to be misfiring and I wanted to remove the 4th cylinder's plug in order to find out if it has been "fouled out" or possibly replace the plug wires and/or coil pack(s).

How do i check of sparkplug misfire on a 2003 ford taurus

Go to Auto Zone or O'Reillys and have them hook up the code reader. The reader, if there is a misfire, will tell you which cylinder is not firing. That's your culprit. The firing order diagram is available online or in the store. It will tell you which plug is which.

Replace the plug. Ensure the gap is set correctly. That should be the end of it. If you really must visually inspect for spark then after pulling out the plug, re-attach the spark plug wire. Hold it by the wire end, where you are touching rubber to protect from shock. Have someone turn the engine over slightly. You wont have compression in the engine as the plug has left a nice size hole on the cylinder. But a turn or two of the key should produce a spark or two on the plug. If you dont see a spark, you may have a bad plug wire.

I'll bet you a $3 bill that your trouble is fixed back at step one. Replace the plug.

I dont have a diagram for you but you shouldnt need one.If you remove one plug wire at a time,replace the plug,and match the old wire(one wire at a time)to the wire of similiar length.repeat that process and you should be alright.All the plugs are accessible just trace the old ones as you replace with new ones
