You can get the coils from Rock Auto.Com

Airtex Brand 5C1584 $40.79 each

You can replace yourself in about 10 min per coil-- tops

There is no such thing as a tune-up

You only have spark plugs to replace every 3 years
If you have the 3 valve 5.4 motor you use the one piece
champion plugs 7989

The oe plugs come out with an odd size 9/16"socket
All replacement plugs are standard 5/8" socket

That is a rip off galore & you should be doing that work
yourself & never ever go to any lincoln dealer with any lincoln

The coils & plugs are $400 alone- if you do,so don't pay more

The proper way to diagnose that-- is with professional software
& run Mode #06 on a road test & check for cylinder misfire counts

I can assure you the dealer won't get it right or use the most commonly used testing for coils or an oscilloscope,so if you
don't want to work on it,go to a shop near you that has been there 25 years with the same owner

SOURCE: 02 navigator misfire #7 cyl still after i changed plugs and coil

You've tried everything but getting the timing checked out. You've done all the other parts of a tune-up but that.

When you changed the spark plugs did you notice #7 was especially dirty or greasy, this could point to a seal being broken or a piston ring that needs replacing.

SOURCE: 2005 Lincoln Navigator. Message says to Check

Most likely the problem you are experiencing with the park assist is a fault in one of the sensors mounted in the rear bumper. I would not consider it to be a major fix, however there will be a few hours labor involved as the bumper cover needs to be removed to replace the sensors.

NEEDS A TUNE UP, DONT SEE SPARK PLUGS


Tune-ups have been long gone for 25 years now

All that is left from those days are spark plugs

I hate to tell you this, but 80% of the vehicles out
there, have had their spark plugs under the ignition
coils for about 15 years,so you have some catching
to do

You can only have have plugs in the sides of a cylinder
head where you can see them, or you can conclude you
have a hemi or top mount spark plugs & the coils are on top

Spark Plugs get replaced every 3 years

The coils you have, only last about 6 to 7 years,
then misfire & eventually ruin the exhaust converter

Your 2005 vehicle:
Should be due for the 3rd set of spark plugs
The 3rd or 4th trans & power steering fluid change (Never Flush)
MAF Sensor gets cleaned at least once a year
Every 3 years--Air Filter,Gas Filter,Cabin Filter
At 100,000 miles you replace the front Oxygen Sensors
At least twice a year you pick up a mechanic & go for a ride
You drive they look at scan tool data,fuel trim,O2,Maf etc

2006 Lincoln Navigator hesitation problem


Why are you charged for someone to look at a vehicle?

Well-- they have decades of knowledge & training & about
$100,000 in tools & test equipment

Just like your doctor charges you $220.00 & the staff does most
of the work before the doctor comes in & no one questions those fees


On that vehicle & that 5.4 V8 motor you had to remove the odd two
piece spark plugs the day you brought it home form a dealer or they
freeze in the head & about 3 break off

There are a couple of tools for removing the plugs
They cost about $70.00 & are on amazon & all tool sites
That job you can do yourself for the price of the tool

Champion makes a one piece spark plug

Lots & lots & lots of info on the internet on that spark plug issue

All was avoidable if the plugs were replaced the first couple months
it was new

On to Oxygen Sensors--The front 2 only get replaced at 100,000
miles on ALL Vehicles

The COP Ignition Coils on a ford only last 6 to 7 years so their
done & most likely have been misfiring for years & RUINED the
Exhaust Converter

ALL you have been told is true, just not explained properly,or why
your not knowing what vehicles require in the way of Preventative
Maintenance actually caused the issues

As they say, you bought it, you drove it, & it is up to you to use the
internet before & during ownership to educate yourself

I've typed enough for now & will say the prices you were given
were just short of fraud & non sense

You can go to Rock Auto.com & look up the spark plugs (champion)
Wells Coils (8) & Walker Pipes & Converter if necessary & your
around $1000.00 in parts --normal wear & tear actually for an 8 year
old vehicle

The 2004 thru 2006 5.4 had injector leaking issues
Most on the 2005 model year those can ruin a converter

IF you PAID a shop once or twice a year to go WITH YOU &
your driving & they take along a scan tool to look at data you
can stay on top of how the motor runs & (again) avoid most
Problems

Is there a heavy duty coil over shock I can use in place of the original rear shocks in my 2002 navigator?


If you mean as a substitute for the Air ride there are conversion kits. Just look in your Browser and search for terms like "Lincoln Air ride conversions", "Rear spring kits for Navigators", and so on.

There are also shocks with Booster springs which can increase load capacity.

In addition, several companies do repair the Rubber bags and you can get what you need from Salvage yards to put your ride back to original shape.

On some of the cars with Air ride, I believe it was $300 minimum for a conversion, for just the coiled shocks, I believe $120 a pair. Anything for a Lincoln Logo you will pay more and often. I have not used any of these kits, so I can not say how good they are or what the Install price is. The Web is the best place to price out these parts.

Repair shop told me I needed a one new coil pack and new plugs. My 2005 Lincoln Navigator has 90,000 miles and has never had "any" engine work other than basics needed. Should all coil packs be changed...


Just change the bad coil. Each plug has its own and there is no difference when you replace a single coil or all. They could have ripped you off with all new coils, but did not.

Replacing all the plugs is a good idea for the mileage and the access. The same main parts have to be moved to get at one or 8.

How do I replace a coil for 2005 lincoln ls


You have 8 coil pack's, to remove undo coil harness then remove small 8 mm bolt slide coil pack out and replace with new one, if replace all do same with all, you will have to work it around fuel rail, but I have never heard of all coil pack's going bad.
