There are only two limp modes

ETC-Electronic Throttle Control-that is from
really bad ignition coils

Cylinder Head Temp -from the obvious


The parking brake is electronic

All it's components you can see under the back
above the rear differential

orIs the water coming from above the floor(front or side windows)(is the puddle big) or from underneath the floor(slowly spreads)? I think you have a lot of water coming in from a leaky window gasket, most probably in the front window.

If I read correctly, you said you changed DCCV, did you bleed the air out of the system? If not this will cause this as well.

No that is just a gadget--forget it

The PCM has no ties to any filters

You should have a log book for preventative
maintenance & years of experience in knowing
what needs to be done & when on any vehicle

You treat all vehicles the same-- mileage or time wise

You change that filter every 3 years

I have the same car

Do it yourself

dealer is too expensive

I have the same car, I bought new

You don't need a shop to work on that issue

You go to Rock Auto.Com & buy about 6 Wells
COP Ignition Coils for about $50 verse $70 at parts store

You only need a 7mm socket to remove the coil covers &
one screw holding any coil you wish to change

I realize you don't have professional tools as I do,or all the
experience with the LS coil issues

I have replaced coils based on a code, which should be PO 301 thru
PO308, not the 355 & letter stuff, although there the same thing, just not
on an LS

I have used scan tool software in Mode #06 to find bad coils

The third & most time consuming way, is what you do & I have had
to do also & the reason the dealers & shops can't resolve the issues
at times

You start with a new coil in the cyl with the PO Code

If you get codes again or many codes & you will,you replace the old
coil & walk the new one to another cyl

Why--because a really bad coil will act up whenever it wants to,once
ever 3 weeks,2 weeks,at every stop light one day & then gone for weeks

I have seen people on this site spend up to $2500 at a dealer with no fix,
when one 50 dollar coil & half hour of your time was the fix

A bad coil will put you into ETC Failsafe & you can't go over 6 mph,that
is the way the system is designed

Better yet- for another $1200 a dealer installs a new throttle body for
no reason ,other than they don't understand the very product they sell
& service

There is no relearn procedure when replacing an ignition coil

That shop has no idea how to work on a Lincoln LS

I have a 2004 V8

Most are V6 so I assume they removed the intake to do
the coils 1 thru 3 & now you have a vacuum leak

Very sloppy work,they never smoke tested the intake to
confirm their work

In 9 years I have never had to do a single relearn on mine

Relearn is something you have to look up & do before you
give the car back. It is not the owners responsibility to do

I would say you have to give the shop one time to resolve

Personally any shop that bad I would stay clear of

2004 Lincoln LS | Answered on Feb 12, 2013


Transmissions are only new one time,off the assy line

Yours is rebuilt locally or you install a reman

I never saw that happen years ago when I owned a trans shop

Doesn't matter what happened you need at least a new case

I would install a factory reman or one from Jasper Engine & Transmission

Read my other post to your other question

If the doors are open,drop the back right seat back,
& crawl into trunk & pull the yellow release tab

OBD2 Vehicles do not use the lighter for battery voltage,
that was obd 1 systems ,the power is in the diagnostic connecter
by your right knee,need adapter to use battery KAM memory
back -up

The seat may only be released from the trunk--.have to check my 2004 LS

2004 Lincoln LS | Answered on Feb 07, 2013


some had a cable release by the drivers or back seat door near the floor..in extreme cases, remove the back seat and crawl thru and release manually

2004 Lincoln LS | Answered on Feb 07, 2013


Try jump starting, charging or at least testing the battery. I had a similar problem when I first got the car off the lot. It had been sitting a while in the cold so when I test drove it they jumped it and it started. I kept it running for 10 minutes after the test drive and it started again to get it off the lot. I got it home and it wouldn't start. It had enough juice to have the lights, alarm and things like that to go, but not enough to get the car to turn over. Whenever I tried, it would make the alarm go off. Give it a try, hopefully thats all it is

most likeley needs a throttle body

2004 Lincoln LS | Answered on Jan 28, 2013


Thermostat has nothing to do with the heat

You have a coolant control valve down low under
the a/c drier on the passenger side, bolted to the
radiator shroud

I have that car,very complicated vehicle,one of the
most high tech ford has every made

Beside that valve there are several other possiblities,
mostly all electronic

Need the experience & all the diagnostic manuals or
I hate to say it,but maybe a dealer,not many shops will
work on a ford or an LS

1) Engineers at Ford have designed the motor to use higher octane.
2) It is supposed Lincoln owners can easily afford the higher cost.

Use the OBD2 Codes you get- to diagnose the Evap System

While the gas cap could be bad- so could six or more other items
in that system, that are causing a leak
