How do i change the spark plugs. And how many do i need for a 2005 mercury mountaineer mariner

4 plugs for a 4 cylinder, 6 plugs for a 6 cylinder and 8 for an 8 cylinder --none for a diesel
pull the coil / lead of each plug ( one at a time ) unscrew the plug using the appropriate tool and replace
when you have to ask these questions it will be cheaper and quicker to get them changed professionally ( plugs cost from $8.00 each for the cheapest to $25.00 each for top quality lines )
AS efi plugs seldom need changing but you have a problem like a misfire, run the fault codes first and have the injectors checked

Is there a fuse for the entry pad on a 1996 Mercury Grand Marquis?

Fuse #8 on the interior fuse panel and 20amp on the engine compartment fuse box, but if either of these were blown you would have several other things not working, door locks from any switch, dash board wouldn't light up, cluster radio heater control and d o on.if all this is working, I would start my testing at the door pad.they get little cracks in them over time and water gets inside and corrodes the switch, pad, internally. .ive done a lot up hete on east coast. .

Cylinder miss fire #8

You have 8 coil packs! Just start the motor and unplug # 7 so you get an idea of how the motor changes! Then unplug #8 if motor dosnt change then you have a bad coil! They run 50-70 bucks at Oreilly

Had the same exact problem on my 2000 Sable. Checked ignition switch. Good. Replaced battery. No change. Replace starter. No change. Starter solenoid engaging when ignition turned on. What it ended up being was an $8 positive wiring cable coming directly from the battery to the starter. Even though it checked good with an ohmmeter.(good continuity) Under load, it became an open circuit. Thus, the 12vdc could not transfer to the starter motor. Save yourself hundreds of dollars and time with an $8 dollar cable.

8 hp mercury motor starts and idels works fine at

Sounds like you need to service your carb as the mainjet is probably partially blocked or you have a choke thats not opening properly or a blocked filter.
