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.

Misfired cylinder 6, replaced coil, plug Misfired cylinder 5, replaced coil, plug Misfired unsure which yet, all of these happening within a week. It will run fine for a day or so after rep


change all plugs with proper ones - they are picky for some reason - do not change number or brand from original - coils were probably ok, - get some injector cleaner and run through it but check for exhaust leak at e g r tube - is a common over looked cause of misfire - a thing to keep in mind is misfire isn't always spark issue. hope I was of some help

Misfire cylinder lincoln ls


Misfire is almost always bad spark plug and/or ignition coil. I wouldnt trust an OBDII scanner to correctly diagnose which cylinder is misfiring. Your best bet is to replace the coils in all 8 cylinders (or 6 if its a V6) since when one goes out it makes the others work harder, meaning that they arent far behind

2000 lincoln ls misfire


In my experience the most common reasons for a misfire diagnostic trouble code (DTC) for a specific cylinder like P0306 which I am guessing is the DTC you recieved without have any other DTC's like a P0300 (random multiple misfire) is either the coil or the injector. There is always the chance you have a faulty connector at either the injector or the coil. It kind of hard to help you completely as I need to ask you a few questions in order to go further. Here are the first set of questions. After you clear the code, does it pretty much come right back ? I know the spark plugs are new but have you looked at the spark plug in cylinder number 6 ? Is it wet or black due to fuel ? I understand you are able to pull DTC's but are you able to look at any freeze frame data with the scanner you are using ? You can reply/comment here or email me directly at csautomotivecars@att.net and maybe we can work through this without having to replace a bunch of parts that don't need replacing. One thing you may want to try which can be a little bit of a pain with the injector but if it is a hard code or a code that comes back quickly after clearing the DTC but you may want to swap the injector (since you already replaced the coil) with an injector from another cylinder. If you recieve a new DTC for a misfire in the cylinder you put the injector that was originally in the number 6 position then more than liklely it's the injector that's faulty. Injectors can get dirty and kind of stick open and drip fuel when it should be off/closed. This will also cause a wet or black spark plug in that cylinder. Yes vacuum leaks and fuel pressure can cause this by the way but in most cases you will also get a P0300 as well.

Where is the coil pack for cylinder 5 located at for a 2002 lincoln ls


Hi, welcome to FixYa.com my name is Shawn and I will be answering your question.

They have an individual coil for every plug on this engine. Do you have a check engine light on if so if you retrieve the code it should be a P030X misfire code the X being a number between 1 and 8 identifying the cylinder that is misfiring. #1 being the passenger side front - #4 passenger rear #5 driver front #8 driver rear. They go in order 1-4 passenger side 5-8 driver side. If this is a 6 cylinder then coil 1 would be the passenger side front coil 3 would be the passenger side rear. Coil 4 would be the Driver side front and 6 would be the driver side rear. The coils are located under the center cover on the valve coves.

I hope my assistance helped you and resolved your concern, if you need further assistance please ask.

My light says ignition coil b. also the primary and secondary.......what is the primary/sec / AT FIRST IT SAYED #6 misfire. also it still has a slight miss at idle and crussin in overdrive . Can you please...


It sounds like you need a coil for # 6 cylinder .LS's have a issue with the valve cover seals leaking oil into the spark plug holes and causing a misfire if this is the case you have to replace all the gaskets for the valve covers clean out the oil and might as well do sparkplugs then too. Its more of a dealer repair then. If no oil in that cylinder try replacing coil and spark plug.

Misfire in cylinder 6. chaned coils an spark plugs still come up as misfire in cylinder 6. CHANGED ignition coil still comes up. What should i do next?


Plugs get changed at 70,000 miles
I would suggest that you use the OEM
Plugs,they are made by NGK and are special
on my 2004 LS,I don't know about yours.

Clean the MAF Sensor with the CRC Product
for that

Change the 2 front O2 Sensors at 100,000 miles

Check fuel pressure at the fuel rail on engine

The coil you replaced on #6 ,even though you
have a PO306 Code,doesn't mean that was the
bad one. It is a COP Coil or Ford thing, you will
learn as you get involved with them

In some cases, you buy 1 new coil and walk it
from one cylinder to the next.

On single coil codes, you may get lucky,on multiple
codes or a really bad coil you won't

Your not using any fancy test equipment and
unfortunately a lot of repair shops have it and
don't know how to use it,including dealers

V6 or V8 ?

These cars are famous for leaky seals where the valve cover interfaces with the cylinder head, at the spark plug journals. They fill with oil, short the coils and cause a misfire. Driving it any significant distance can destroy your catalytic converters ad unburnt fuel ignites therein, creating inferno-like conditions and a fire hazard too. You'll get a "300 code", such as 301 if cylinder 1 is misfiring, 302 for # 2, etc. Pull the coil off the spark plug for that cylinder and if it is moist at all, that's your issue. Have new seals put in, or you'll just keep blowing coils at $50 a whack.
