Question about 2000 Lincoln LS

1 Answer

2000 Lincoln LS 3.9 with intermittent misfire problems that is accompanied by a knocking type noise from the transmission bellhousing. Have replaced the Crank shaft sensor, Cam sensor, Cool packs on several cylinders. Keep getting 303 code even though 3rd cool pack has been replaced and various other 300 codes. When the transmission is disconnected, the noise stops, but 300 and 303 codes return after being reset. I have also switched the injectors around.

Friend, do a compression check on all cylinders. The one, most likely #3, will show low compression because of a bad valve. This causes the engine to idle rough and once it goes into overdrive the whole vehicle shakes I'm sure. And since you've swapped the injectors around, and it still chows a 303 code, it wasn't #3 injector causing the misfire code. Keep all this in mind friend, this problem is indigenous to all these V6's.

SOURCE: 2005 Lincoln Ls 3rd Brake Light Wiring

The best way to wire a third brake light is to run the wire directly from the brake light switch on the side of the steering colum to the light. You will need a test light to find out what wire lights up when you push the brake pedal. Then you can splice into it when you run your wire to the rear light.

SOURCE: check engine light on.code is po113.sensor 1 circuit high input

If the only code you have is a P0113 then the answer to your question is no it can not be the oxygen sensor. P0113 indicates that the IAT sensor is reading at -46 deg F. With the computer thinking it is that cold it will need lots of fuel,cold air is more dense and com-pack so more molecules of oxygen and therefore needs more fuel to keep correct air/fuel ratio.
Do you have a way to measure voltage across the sensor?
You should have about 5V coming into the sensor and around 1.5 to 3.0V(depending on the temp) leaving it.

SOURCE: 2004 Lincoln navigator misfire on cylinder 8 error code p318

Replace the coil pack once more. I went through 2 new ones on my f150 on one cylinder. One worked, the other didn't (both new off the shelf). Condensation build up in the boot caused mine to misfire. Anytime you replace a coil pack, squirt a little silicone grease inside. This will prevent condensation from hitting your plug. Fords are notorius for this problem, especially if you live in a humid area. Also, make sure and clear the codes after you make the repair.

A bad coil pack can foul out the spark plugs. I have also been told the computer might need to be reset for around $100. You must use Motorcraft OE plugs for this car to run at its best is what my mechanic told me.

Have a lincoln 2000, it's supper shaky and also has a noice not so sure wat could it be they tell me the coils


Please describe the 'super shaky' and the noise. The following might help.
Well, I'm not an expert but your description matches threeissues I have seen with my LSs (I'm on my second 2000 LS) and others I waslooking at buying. The immediate concern is that you say you have a noiseand I say DO NOT DRIVE THIS CAR ANY FURTHER! If the noise is kind of a whine,you may be okay for a while but if it's a high pitch and/or loud groaningnoise, STOP, get out of your car, get a flashlight, and check the ball jointsand/or the upper steering arms (I believe that's what Ford calls them). The LSlower ball joints and related upper steering arm that are, in my estimation,poorly protected with a CHEAP rubber protector that deteriorates anddisintegrates to nothing well before the life expectancy of the front endjoints they are supposed to protect. In any case, this would be a big concernso check this item first. Grab a flashlight and turn the wheels all theway, (best results = to the left for the d-side, right for the p-side) so youcan inspect the joints. That being said, "coilpacks" and/or faulty spark plugs are the most likely culprit for the"super shaky" if it's more like bucking and jerking and affecting duringacceleration or when you're cruising. Find yourself an auto store that withread your emission codes and look for a P030# code, wherein the # is thecylinder number (V8 motor). For example, a P0304 code means a misfire in the #4cylinder. BTW - the number 1 cylinder isthe front RIGHT (psngr-side) cylinder. The code gives you the cylinder number that is misfiring and it could bejust spark plugs as they generally last 75-115K miles.The other thing it could be is your transmissionslipping but I don't know anything about transmissions.

How often to change tranmission fluid on a 2002 lincoln ls


Hi Gary,

There is a small dilema here. The Owner's Manual for your Lincoln says to refer to the Maintenance schedule to find the proper interval for replacing your transmission fluid. Here is where the problem arises: The Maintenance schedule published for your vehicle says to replace the transmission fluid at 30,000 mile intervals for several transmission models. Then it "excepts" the models that are not lsted by transmission model number in the preceeding text - yours is not listed.

Then, when I go to the service manual and search by your vehicle (2000 Lincoln LS) it says to replace the transmission fluid at 30,000 mile intervals without any exceptions.

Here is what I recommend to my customers:

CHECK the fluid every 30,000 miles and REPLACE the fluid and filter every 60,000 miles. I have found that this works for almost every make and model out there. I have several customers with over 300,000 miles on their cars that have never had transmission overhauls.

For free PDF version downloads of both the Owner's Manual and the Maintenance Schedule (3rd printing) for your vehicle, click the links below.

Oil in 2000 lincoln ls is 4 quarts low after only 3 months, now there is knocking in engine.


Hi!!

This noise can mean bad news, but, let's not panic and try something.

Some times when oil level gets too low, the lifters discharge and valves start making a quick knocking noise that doesn't quit even if the oil level is normal.
and increases when you step on the gas.

This happened to my friend's car and fix the problem adding a Valve Quiet oil additive, in a couple of minutes the noise was gone.

If this is not the noise you are hearing, take it to a mechanic shop for repair, preferably on a Tow Truck, because the more you run the engine, the more damage you can cause to it.

Good Luck

I HAVE A 2000 LINCOLN LS. IT IS MISSING BAD AT AN


What you do, is get to a shop,NOT THE DEALER, that has a professional scanner and oscilloscope. Not a code reader. Now you know that codes alone DO NOT tell you what's wrong and never what to replace. I have a 2004. This is Fords most complex vehicle ever. Sort of a test bed for them and a nightmare for us. You will need to find the best driveability tech you can find to work on it. It won't be cheap,nor a quick fix
