SOURCE: can bad fuel injector damage spark plugs on a 2005

Bad injectors cannot make plugs bad.
Plugs are cheap compared to injectors.
I've replaced my own plugs, so I cen't tell you the labor to replace them.
If something needs to be fixed you can bet they will charge whatever they can!

I have 2007 Ford Expedition, I had replaced both catalytic converters twice. And it sounds like it's going out again. I'm burning gas twice as fast. Highway I'm getting 12 mpg.


Replacing your catalytic converter will not resolve your excess fuel consumption problem. Cats only assist in emissions, and excess fuel that gets to them, breaks them down. Therefore, you need to find out your fuel problem to no longer replace the cat.
Could have leaking fuel injectors, or bad valves which do not allow for a better and complete combustion. Bad sensors could also cause problems.
Start out by performing a complete and proper tune up. Then check to see if you have any codes in your ECM.

There are several thread repair kits for that

I'm supprised you haven't used the internet
to look at all the info on that problem,do that

TryYou Tube Video also

It went on for about 8 years & Ford never did
a thing about it,just kept selling defective cylinder
heads from 1997 or 98 until 2003,then came out
with the 5.4 - 3 valve V8, that has spark plugs that were two
piece,that broke as well,and an odd ball 9/16 nut to remove them ,as well as fuel injectors in at least 2003,2004 & 2005 that leak & ruin the exhaust converter & in some cases hydraulic

California illegal catalytic converter ford expedition 2003


Because the cat that is approved for California is "finer tuned" than the other 49 states. California emission standards are the toughest in the country, so many engine and emission parts are made just for those standards.

If my 2005 Ford Expedition needs a major tune-up, does all 8 coils/8 sparkplugs need replacement or can I just replaced the bad ones?


I'm have to tell you, there is no such thing as a major tune-up

Also, there have not been any tune-ups in 25 years

All that is left is Spark Plugs

You only replace a COP Ignition Coil, when it fails

You need professional test tools, to find the bad coils,
unless your just going to walk a new one, from one
cylinder to the next, for a few days,until you get the bad ones

The engine light is on and blinks sometimes. Car feels likes it wants to turn off when I am a complete stop. Recently the car is wasting too much gas!


Probably a bad coil or sparkplugs...If the engine light is flashing,,that means it is doing damage to the catalytic converter...Which is very costly..Up to 2500 dollars to replace exspecially if its a 5.4...Need to have that fixed before you hurt the converter

Check engine ligh on and then starts flashing


You are having a catastrophic misfire that will destroy the catalytic converter unless repaired soon. You may need a tune up or a 02 sensor repaiered but you will need scan tools to test what codes is being thrown.

Why is my 1997 expedition showing a misfire on number 2 cylinder OBD code PO302. Also I am getting code readings PO174 andPO171 system to lean on Bank 1and 2


PO302 is being a misfire, could mean the plug is bad or the coil is bad for that cylinder. Which can give you the misfire reading and the system to lean codes. Check the #2 coil for firing.
