Question about 2001 Lincoln LS

1 Answer

My 2001 Lincoln LS V8 3.9 seems to have a slight miss when in overdrive about 1700 rpm's on an upgrade..you give i. t gas and it bucks and a slight miss. Have changed one coil pack, new spark plugs, new air and gas filter..gas filter was really dirty...did not change the rear filter in gas tank. No check engine light comes on. No diagnostic codes appear because the car does it intermitently.

When you changed spark plugs did you notice any oil on the insulator or wire plug? Or any oil in the hole that the spark plugs are in? This model of LS were built with gaskets that seem to always fail. Lincoln came out with new gaskets in 2002 or 2003. If there was any oil in the above mentioned places your coils (COP Coil on plug) could be shorting out due to the oil degrading the insulator on the cops.The fix for this is to replace the valve cover gasket set with the upgraded set. Also it's almost impossible to find which coil is bad, and I recommend replacing all eight of the COPS. You can find them online pretty reasonable. I have used these and they seem to perform as good as the Dealer parts, but at a fraction of the cost. This solved the problem on my 2001 LS V8. Also these cars are known to have problems with the timing chains, which could also cause your problem. The adjuster shoes that keep the timing chain tight are plastic and wear out and come loose. Some times causing the engine to jump time and in the worst case could allow the pistons and the valves to come in contact. That will destroy the engine.

you have to get a reading of the on board diagnostic system, Autozone read it for free . then they will print a code for you that will show which part is causing the problem (oxygen sensor or the catalytic converter )

SOURCE: air conditioning recharge

look back towards the firewall in the low side AC line, that is the larger of the 2 lines, the charging port is in that low side line.

SOURCE: I need the location of the low pressure ac port

The lincoln better idea engineers put the low side freon port in a peculiar place.. You will find the low pressure port near the compressor under the car on the driver's side. You will need to put your car on a lift to get to it. Once you raise your vehicle, take the plastic shields off and you will find the compressor...yup...it's a tight spot.
Hope i was able to answer your question...be safe.

If one of the engine components is acting up, you should get a check engine light and have codes for the components. If the light is not coming on, it could be a suspension or mechanical problem.
Low fuel pressure could also do it.

I would go with bad COP Ignition Coils

More likely you have several bad all at once

Common problem with ford & lincoln cop coils

No you don't need any codes for that to happen
& the PO 300 codes on those are not always correct.

I have had the fuel gauge code also in my Lincoln Ls &
lots of others.

Just work on the coils & disregard all codes

Not the tps, not the gas pedal, not the tacm on throttle
body.

I have seem a bad battery do some odd things

This sounds like you have a pcv hose that has become an open vacuum leak. It is located under the upper intake, or given the year your air filter box may not be correctly sealed and possibly have a mass air flow sensor concern.

Most likely caused by a failing coil pack. The dealer can do what is called a stress test on them to see if they are bad or not but this is pretty labor and time extensive because they have to be removed one at a time to test them. If you have access to a scan tool that will read mode 6 data it may show which cylinders are showing some miss fires and you can try and just replace the ones that show a miss fire and see if that works.
