Hey cbrooke
Some things to check would be the wires, look for arcing in places where the wire may have "chafed" against something, the back side of the engine is a common spot. I would also recommend you get the car scanned for codes to see which cylinder is misfiring. Let us know

how often do the spark plugs need to be changed in a 2004 mercury sable ?

if not have been done you engine is getting ready for it
if you have a problem make sure you check and or replace the coil
good luck

Hi I need to know the location for spark plugs to a Mercury sable ls premium and the firing order. I think it's 142536 but not sure but I need their location.

Hi Rachel,

I am going to provide information for a 2004 Mercury Sable 3.0L. If you have the dual overhead cam, it will be the same. I just double checked.


Firing order .................... 1-4-2-5-3-6

The two pics below indicate cylinder location and coil information for each cylinder.

Let me know if this helps.

I need a specific spark plugs diagram for my car and how to change the spark plugs instructions. Also I need the serpentine belt diagram specific for my vehicle and how to instructions on how to change the serpentine belt along with information as to which specific auto part serpentine belt I should purchase. Please help. Thank you for any and all assistance.

Do you know if you have a dual overhead cam engine or a single overhead came engine? I attached the procedure for the spark plugs. They are the same on either engine.

The belts are different. The SOHC is the first diagram and process and the DOHC is the second.

Here is a video on how to change spark plugs. Clearly it is a different engine but the process is about the same. Also, a guide on how to change spark plugs.
