U codes are communication faults between the different modules present on your vehicle. The PCM has to maintain control via separate modules that monitor and control every aspect of it, from engine and emission control,transmission control, anti-lock, traction control, lighting, hvac, suspension control, etc...To diagnose these codes requires a quality scan tool and a technician who is experienced with these systems.

Lincoln navigator 2000 p304 code misfire changed coil and plugs still havin same problem


Hello puma...i think you mean a P0304 code?

A P0304 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #4.
You have covered a couple of the possible causes...here is the list of possible causes that you can use to continue you troubleshooting...Make sure that you CLEAR the code after each repair is made. The fuel injector would be the next i would check, it could be dirty, defective and not firing. The color/condition of the #4 spark plug would give you an idea. Hope this helps...

  • Faulty spark plugmag-glass_10x10.gif or wire
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector
  • Burned exhaust valve
  • Faulty catalytic convertermag-glass_10x10.gif(s)
  • Running out of fuel
  • Poor compression
  • Defective computer

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.
