Lincoln LS misfire problems

Filed Oct 24, 2014 · Engine · 162,000 miles · KY

While driving the car it misfires it doesn't want to go on acceleration..it is leaking oil into the spark plug wells and affecting coils..there was a extension warranty on these parts.but it was 10 years or 100000 mile . I didn't purchase this car till after it already had more than 100000 miles so I was unaware of these extensions and time frames..I spoke with ford/lincoln and basically told the extended warranty would not cover.I feel this should be a recall not extended warranty.

Car hesitates on acceleration since it was new. Took the car to the selling dealer and they could not find a problem. The condition got worse. When traveling down the highway the car starts bucking and misfiring. Took the car back to the selling lincoln dealership (sesi lincoln mercury). They dealership said the drivers door needed adjustment. This made no sense to me and did not fix the problem. The car went out of warranty shortly after that. Now check engine light comes on intermittently and car hesitates, bucks, stalls and runs rough, misfires at highway speeds, and mil starts flashing. The cowl plastic piece has a poor seal on it that lets water onto the engine electrical system. Ford issued a technical service bulletin that addresses this issue and ford admits that seals need to be replaced. This may not be the only problem with this cars electrical system, but it is a big problem. This is a design defect, nothing a customer can do to prevent this. Ford should have recalled these cars and fixed them at no cost. The fact that their dealerships were hiding the real reason for this misfire and not repairing the vehicles under warranty is breech of contract. Ford should be fined and punished and forced to recall and repair all of these cars. I am an ase master mechanic. I teach automotive service technology at the college level. This should not be happening. The car was garage kept and very well maintained, it looks new. I found that # 6 cylinder had a p0306 coil misfire dtc. I had to remove the intake manifold just to see the coil on plug set up on the passenger side bank of engine. Turns out there is poor sealing of the windshield cowl area and water runs directly onto the engine and engine electrical system. The water shorts out the coils, spark plugs, computer and electrical system. The car is not safe to drive. This can happen at any time especially when wet.

The plastic tensioners that the manufacturer put in broke causing a huge engine misfire. The vehicle had these plastic tensioners but a recall should have happened as it appears someone knew about this since manufacturer came up with generation ii and generation iii and these added generations, are made of metal which should have been in placed when they first built the engine. Awesome engine, lousy tensioners that at high speeds, could have cause me to lose control and perhaps got into an accident or killed myself or kill some one else. Please let me know if there is a recall for these tensioners. I am about to spend 1,500 top replace them.

Tl* the contact owns a 2005 lincoln ls. The contact stated that the ignition coils were replaced frequently before 100,000 miles. The vehicle was taken to the dealer for diagnosis where it was stated the ignition coils misfired and needed to be replaced. The vehicle was repaired but the problem persisted. The manufacturer was notified. The approximate failure mileage was 100,000.

Car act like it stalls/skips/misfires around 2200 RPM, engine shuts off & "etc engine failsafe mode" is indicated. Diagnosis as electronic throttle control resulting in an unsafe driving condition typically when accelerating on freeway or causing complete engine shutdown. As indicated on a wed chat page this lincoln ls engine failsafe mode is a significant problem when the car won't go past 20 MPH & then you get to play a game of lets dodge 70 MPH traffic w/ semi-trucks (where the minimum post interstate speed is 45 MPH). From several web sites, it appears this error is a common safety concern with a number of lincoln ls's.

The engine failures began on july 28, 2005 and have continued through this date. This engine should have been recalled. The types of problems cause the engine to create erroneous mechanical readouts preventing the vehicle from passing state's emission inspections. The engine shuts down due to faulty plastic tensioners causing the timing chains to become loose, thus causing engine failures. I'm lucky I was not going any faster when my engine failed twice causing me to lose my steering capabilities, etc. Most mechanics are replacing ignition coils because they are getting misfire readings on specific cylinders, however the problem lies with the timing chains that go out eventually. Currently, I have four diagnostic readings on my engine stating that number 4 cylinder is misfiring, when indeed two mechanics are stating that the timing chain is the problem and another expert familiar with this problem sells the specific kits to try to correct this known problem of ford's. Check out this website for more information: http://stores.christophersforeigncarparts.com/-strse-template/about/page.bok. I have had all 8 cylinder ignition coils changed; spark plug boots; and valve cover gaskets replaced and still these are misfiring. Lincoln knew of the problem with these models and changed the factory warranty on all models after 2002 from 50,000 miles to 80,000. Please refer to edmund's blog site under lincoln ls for additional owners experiencing the same thing. Also, I filed a consumer complaint back on 10.25.2007 at the state of missouri attorney general's office. Ford was made aware of the problem and did nothing to remedy the situation claiming the car had too many miles and was too old.

Going from a stop or accelerating on the high way the car will throw a etc check engine light and wont move over 3-4 miles per hour. Then goes into a very rough idle, until one turns off the car and restarts then drives fine for a few mins the goes right back into the etc engine fail mode.... Very dangers if merging onto traffic. Almost been hit several times cause of the problem.

Car starts and runs rough, then surges forward. Have to hold the brake hard. Car then stalls and gives "etc engine failure". Upon restart car will run fine for a while. *tr dealer cannot identify the problem, as it does not consistently throw a code, replaced the coils

Ford lincoln mercury~manufacture warranty extended on ignition coil - but each time ignition coil goes out it causes numerous "other repairs" costing $900+ each time.~ vehicles begins to run rough, the temperature gauge goes to top, the car looses power (while in traffic even though foot on accelerator) will not accelerate~ 5 times in less than 11 months~ these "other repairs done each time ignition coil is replaced should be covered under extended manufacture warranty. (incidents june 2009/ october '09/ january 2010/ march 2010/ april 2010).

I have a 2004 lincoln ls that started to run rough so I replaced the air filter. This did not help so next I replaced the spark plugs. This did not help. The things that I have done up to this point started because my car started missing and running rough however I have found out that it was just the beginning of a bigger problem in that the car was and is pumping gas into the engine and air intake to the point that it is coming out of the exhaust system in an amount that causes a steady stream and it pools under the car. The intake fills with fuel to the point that the air filter gets soaked in gas and I have to take it off and dump it out. This has been going on for 3 weeks now and I am afraid to drive it. The car has fuel injectors??? The company and the dealer have told me to bring it to them and they will fix it however I will have to pay for it. Everything on the car is controlled my computers even the gas flow and pedal that controls how fast I go. To me that is wrong.
