Most common causes are a bad plug or plug wire, low cylinder compression, water in gasoline, engine timing problem, or exhaust system plugging (usually the catalytic converter). There are many other causes related to one of the many sensors on the engine (such as crankshaft or mass air flow sensors) or a problem with the engine computer or spark timing modules. This list goes on ...

Check engine light on and flashing, car shaking, all of a sudden


you have a bad engine missfire. a flashing check engine light means you are in danger of damaging your catylitic converter and you should scan the car. most causes of missfires are plug wires and or coil pack.

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.

Sounds like the Catalytic converter needs to be looked at or replaced.
