Not spark plugs. Never was.
Bad coils.
Switch the COP Coil for the misfire cyl,and see if 300 code moves with coil.
Does it go into Failsafe or just get the MIL Light on dash?

    Not the wiring harness.



    It is the coils. One coil or more are spiking the PCM (power train computer) that spike is setting all sorts of codes ,some related some not.

    The new coil may be and most likely is good,but it still shows up as a PO300 code.

    If you weren't the one who worked on it ,get involved.

    Buy one new coil,start at the back of the row of cyl that has the misfire and install the new one. If you still get a misfire put back the original and move the new one to the next cyl, even if that was where the other new one was installed.



    I just had a situation with my Lincoln LS where a coil spiked the PCM and that spike came back on both sides of the Throttle Position Sensor,then back to the PCM and shut it down,and put the vehicle into ETB Fail Safe ,and you could only drive 5 mph. These issues are common on fords and are outside the factory manuals. That is why people with an LS spend $4000. or more at a dealer,while they throw parts at it. Fortunately I do my own Diagnostics for some 46 years. These issues go on for weeks, until you come up with a solution that defies logic.



    You will need to buy or borrow an inexpensive code reader,so you can check codes,every time you get a MIL Lamp on dash. Write the codes down,then clear them,and switch your new coil around.

    i HAVE BEEN GETTING THE PO316 CODE FOR THE LAST 3 MONTHS. I HAVE FOUND 7 OTHER LINCOLN AVIATOR OWNERS EXPERIENCING THE SAME PROBLEM. BETWEEN THE RANGE OF 40-60 THE TRUCK STUTTERS, STAULS AND RUNS EXTREMELY ROUGH. WE ALL HAVE LAREADY CHANGED THE COILS, COIL PACKS, SPARK PLUGS, FUEL FILTER, THROTTLE SENSOR, CAM SENSOR, CRANK SENSOR AND ARE LEFT WITH THE SAME PROBLEM. I HAVE ALSO HAD 3 LOCAL MECHANIC SHOPS RUN 1 HOUR DIAGNOSTICS ON THE TRUCK AS WELL AS A PERSONAL MECHANIC AND THE PO316 MISFIRE CODE IS VERY VAGUE. IF ANYONE HAS A RESOLUTION TO THIS PROBLEM PLEASE LET ME KNOW.

    THANK YOU

Missfire on cylinder 8 on bmw 545


move the ignition coil to another cylinder and see if the miss fire moves. If so replace that ignition coil. If the miss fire stays on that cylinder it is more likely the fuel injector. Was their carbon on the spark plugs when you removed them? This is indicative that the fuel injector is gummed up.

i would definately replace the coil. pretty certain that will solve your problem. do not drive with misfire or that can cause fruther damage such as catalyst failing, which is prety expensive.

What does the code "misfire on bank 1 mean" on a diagnostic code for a 2000 lincoln navigator mean?


Do you mean "missfire on cylinder 1", code P0301? If so, that means that the computer has detected incomplete combustion in the #1 cylinder, which would be the front passenger side cylinder. There are many potential causes to a cylinder missfire ranging from worn / bad ignition components, clogged / bad fuel injector or even internal engine damage.

However the most common cause, especially on ford vehicles is a bad ignition coil. When trying to determine the cause of a missfire on an engine such as the one in your Navigator i start with removing the plug and checking for carbon tracing, excessive plug gap or contaminants on the plug. If that checks out ok i then swap the ignition coil from the missfiring cylinder to one that isn't. For example, I would swap the ignition coil from #1 to #2 and clear the codes. Then drive around until the light comes back. If it comes back with a missfire on cylinder #2 then you know the cause is the ignition coil and it has to be replaced. If it doesn't then it is something else causing the missfire which will require a bit more diagnostics.

How many miles are on your Navigator? Have the plugs ever been replaced? If you have close to 100k it would be a good idea to replace all of the plugs. Be careful when removing the plugs, it's not difficult to pull the threads right out of the head when removing the plug.

They are the ignition coils, the spark plugs are under them. When you have them off before pulling the spark plugs make sure the holes the plugs are in do not have oil in them, if so you will need new coil boots, plugwires and a valve cover gasket as well.

Missfire in cylinder 2


I assume you know the problem is a misfire in #2 cylinder from checking the diagnostics code. Although these codes can be helpful in narrowing down a problem they lack specific details. In the case there are several possible items that could trigger the engine fault code P0302

These include:
  • Faulty spark plug or wire
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Running out of fuel
  • Poor compression
  • Defective computer
Before you spend any money to resolve this you need to narrow this list down even more. Start by pulling the plug. Do a image web search on "spark plug diagnosis". This will give you pictures of plugs with a variety of problems to compare with yours and give you an indication whether or not the plugs need replacing. Next if possible switch #2 plug wire with another. Make sure you switch both ends (coil end and spark plug end) of the spark plug wire.
These are the no or low cost options. Beyond these you will need to start replacing items like the Ignition Coil and O2 sensor.
If you are still having the problem after checking and/or replacing the items listed above, your next step is a compression test on #2 cylinder.
If you get to this point please repost here with the results with the wires and plugs and I will give you the steps to follow with compression testing.
Hope this helps.
