Question about 2005 Mercury Mariner
Not move at all plugs are bad i think what could this be
Need more info
How many Spark Plugs did you remove & what do they look like?
Have you checked for codes?
Have you had a professional scanner on it, to look at fuel trim
& oxygen sensor data
Have you checked fuel pressure?
Is the exhaust converter blocked from years of cylinder misfires?
Did you buy it used & bought someone problems?
If you never replace the spark plugs every 3 years & stay on top
of the well known & all too famous ford ignition coil problems, you
have what you have.
Need to know more & what motor you have

Have you checked the positive connection from battery to starter? this connection has another feed that runs the rest of the car. Its either loose or corroded. Take battery terminals off and soak in baking soda, water and 2 drops of dishwashing detergent. If any corrosion is present this mixture will foam and remove your corrosion.
Its odd that car dies Are you sure you do not have a dead cell in the battery?

SOURCE: I am driving down the
Now you have to stop using it,sorry
You have two main Fail Safes
One is overheating
Yours is IGNITION COIL MISFIRES
Without getting in a long technical story
the individual coils you have COP Ignition System,
either slowly fail and set no light,or set a code
In your case it doesn't matter because the codes won't help much
You most likely have a really bad ignition coil
It does not ground out as it should in the PCM (computer)
That spike comes back on the TPS Sensor (throttle position)
and then you lose the TPS normal Data that is the result
of where you push on the gas pedal
At that point there is no way to adjust fuel injector pulse,so
it starts killing cylinders and eventually goes into ETC Fail-Safe
Your Done-- Also there may not be many professionals that
will believe me. Been there done that.
Ideally a shop that actually uses an oscilloscope can solve
which coil is bad
You can buy 1 coil for $60.00 & walk it from one cyl
to the next and after a week fix it for $60.00
I will tell you, people have spent $3000.00 at dealers
& got zip.
In the event my story if off,
your next problem would be the
TACM (throttle actuator control motor )
That will be your codes. Do Not let the codes
guide you or your repair shop. The throttle body
is $700.00. If you do need one, you better be installing

here are a few symtoms of a BAD IGNITION COIL. the car will spit and sputter.
If your vehicle is getting a lot less mileage for the gallon, you can also register this as a sign of ignition coil failure. When less power is reaching the spark plugs, your vehicle will struggle and use more fuel to compensate for the lack of power transfer.
Engine Misfiring Trying to start your vehicle when the ignition coils fail will result in a rough ride. Your vehicle will cough and splutter regularly and when you drive at higher speeds, your vehicle will **** and spit. It will also vibrate when you are running idle at a stop sign or intersection.
Vehicle Stalling With ignition coil failure, your vehicle will have irregular sparks emitting to the plugs to keep it running. This will result in stalling. When you bring your vehicle to a stop, it may just shut off totally, thus leaving you needing to restart it.
Coil Failure If your spark plugs are worn out, it forces the ignition coils to operate at a much higher output. Keeping your sparks plug in optimum condition can reduce your chances of having ignition coil problems. Some simple regular maintenance will save you a lot of grief. hope this helps you out !
