How can you tell if you rock modular is out? The shop say I need one $1100 for my 205 Lincoln LS V6,3.0 and there no guarantee that will fix problem no signals to plugs,coils and Injectors

Replace the spark plugs every 3 years

HAVE TO USE OEM-- NGK -- Plugs (Rock Auto.Com
or NGK web site)

I said OEM Tip Config,NOT ford parts,they
were NGK off the assy line. The ford ones are the
WRONG tip,those folks don't care!

Replace ALL the COP Ignition Coils

The coils are your ONLY Problem

I know because I have a 2004 L/S & ten years diagnostic
experience with them, with professional tools

You only have 2 Fail Safes
one for overheating & one that says ETC

Don't even try to figure out the obd codes or the etc thing
Take too long to explain

The dealers can't fix that car,the coils when they get really
bad spike the drivers in the pcm & you loose tps signal & go into
etc failsafe & can only go 6 mph

There is no factory manual that tells you that & your etc on a
wiring diagram is the app or gas pedal,but on the obd codes it
is the throttle body P2100 codes that point to the motor or
tacm,& that is not the problem

So the answer is-- no one likes or understands that car, nor can they
fix one,so replace all the coils yourself,they only last 6 to 7 years

Only need on 7mm socket & get the coils from RockAuto,Com
I use Wells Coils

The front Oxygen Sensors have to be replaced at 100,000 miles

Better be changing that Tran Fluid on ALL your vehicle every 2 or 3
year or they WILL FAIL I guarantee it & power steering fluid also

P 1650--Power Steering Pressure (PSP) Switch Malfunction
P 1702--No Such Code
P 1703--Brake Switch Out Of Self Test Range (Check Stop Light Bulbs)

PO 708 see note 6 Go to work shop manual trans section 307

I have that same car

You need to start with a scan tool on it

I won't say you need a dealer, but the shop will need a data
base & like the LS or they will be wasting their time

Most Hi-Tech Ford ever made so far

Hey Chelsea,
I would have the transmission fluid and filter changed and see what happens. If this does not fix it... time for a transmission repair shop trip.. find a QUALIFIED professional to do the work - THAT GUARANTEES THEIR WORK!!

Agreed Peter. The codes will tell you what to check, not what to replace.

replace cooling temperature valve.

I have a wiring shop manual. I will look up what you need. No way to scan and send to you. Tell me in detail what the issuses are.

Stop driving it,until you change the Tran Solenoid Pack,inside the oil pan.
$332.00 wholesale
If you go to a shop,it will be more,plus labor.
If you go to a dealer,you can make a mortgage payment,just to fix your car

Very likley could be electrical, and the p[arts may have niot needed replacing...sounds like they just took out parts and replaced as a guess we will see if it fixes it deal.

Take it back and have them make it right.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Tires need to be balanced. Take it to a tire shop and ask them to balance all 4 wheels. Problem will be fixed.

first thing is the engine light on?
these cars had problems with the on plug ign coils and if this is a misfire the comp will tell you which cyl is the problem.
