It could be plug wire, the spark plug, or the fuel injector.
If injector, try Chevron Techron Fuel tank additive first. Add one bottle to 1/4 tank so it will be more concentrated.

My engine light is on all the time after i warm it up when i start driving its misfireing bad once i let up on it the light stops blinking and it stops missfireing until i push on the gas


Sounds normal when you have a cylinder miss.
The flashing light means the problem is serious.
You would have the computer scanned for trouble codes then research the codes. You should get a code telling you which cylinder is not providing power and you check the ignition and fuel injector for that cylinder or cylinders.

Where is the fuel composition sensor


2000 FFV Taurus has a FCS mounted to the strut tower not sure about the later years


Ford has eliminated the FCS sensor on the Taurus for model years 2000 and newer, and only uses fuel trims and O2 activity to calculate alcohol content.

My check engine light come up w/ all these code P0305,P0440,P0441,P0446 what's wrong Thanks


po305 is related to missfire on #5 cylinder
po440 is related to fuel tank pressure
pO441 is for evaporator purge flow malfunction
po446 relates to vent control valve electrical circuit malfunction

missfire is seperate from the other codes
as for the other three codes replace the vent control valve solenoid located near the charcoal canister the oth3er codes can relate to a faulty solenoid

after replacing light will only go out if you clear through a scan tool or three drive cycles of over 10 min each

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.

you may try your rotor button and distributor cap. and spark plug wires. try your map sensor also they tend to cause a lot of misfiring if they go bad.hope this helps.
