    this is not a DIYer job, it takes a professional Ford tech 3 hours, all the coil packs must be removed and lots of parts removed to access the plugs. I tore my rotator cuff doing these engines spark plugs. The check engine light doesn't mean the plugs need to be changed, u understand that right?

It does not take 3 hours to change spark plugs..I will suggest you get the right equipment to do this job.Get the right tool that can sit on the spark plug and unscrew....You will need to disconnect the coil pack that sits on top and disconnect the wires if needed.From there it is self explanatory.

My 2003 Ford Expedition seems to buck back and forth between 40 and 50 mph. the check engine light is not on and i just changed the fuel filter. It has 104000 miles, and I just bought it last year. Any...


Has it had a tune-up yet? (New spark plugs) If not, you're due. Also, have the shop test your coil packs - a very common problem with the Expeditions. I had my plugs replaced and No. 2 coil pack replaced recently for around $340. I'm a handyman, but would never attempt to change the plugs on mine myself - too much could go wrong- breaking a plug off, special tools, etc.
This should fix your problem.

2003 ford expedition... shaking when driving and during stop. check engine soon light keeps flashing. recently had spark plugs changed.


will try to help.the shaking during braking may be a warped brake rotor,shaking while driving is in the wheel alignment. you have several issues to deal with.as far as the engine light flashing,check all your fluid levels in the engine. oil,low coolant, brake fluid,transmission fluid. top off fluids as needed. you can reset that engine light by disconnecting the positive cable from the battery for 10mins.this will reset the cars computer. but if you have a sensor or other issues,that light will come back on.the only way to know for sure is to have it code read a garage or dealership will be able to plug it in to get the codes for you.hope this helps and thank you for choosing fixya.com

I have a 2001 Ford Expedition 4.6 4WD. Service engine soon light came on and when checked at parts store diagnostics said cylonder #2 miss firing. Is this a coil pack because we can't find plugs,...


If you do not see a distributor or spark plug wires, then you have a coil over plug system. Changing the coil pack is as easy as removing the hold down bolt and lifting the coil pack off the spark plug. Other things should be checked like signal to the coil, the fuel injector signal and the spark plug

My 2003 ford expedition reads a code 0303= 3 cylinder misfire, which side of my vehicle would that be on and could replacing ignition coil and spark plug fix it and stop the lose of power and hesitation?


Third cylinder back on the passenger side. I'd recommend changing all 8 coils and spark plugs. These coils don't last long, and once one goes, more will fail soon after. This job also requires removing the fuel rail to gain access to the coil and plugs. I personally have the same SUV and went through the same issue!!

My 2003 expedition is idleing and running rough


Its recommended to replace all coils at the same time you replace the plugs. I had the same problem @62000miles, changed the same part, including injectors at the ford dealer. It just got worst, I replaced all the coils and engine ran like new.

Missfire 2000 expidition


there isn't a trouble code that indicates a bad coil... there are misfire codes that can possibly lead to a plug, coil, fuel injector, low compression, or a number of other things. it is possible to have 2 more bad coils-if youve had the engine compartment detailed and they got them wet, that'll do it. other than that it is hard to see 2 coils going at 1 time. spark plugs themselves are more likely.

Changing spark plugs


Changing the spark plugs on a 1997 Ford Expedition 5.4L engine takes patience. Remember to start this project on a cold engine! I started on the passenger side by locating the Coil over iginition coils and cleaned out all the old dirt using some compressed air. Then I had to disconnect the electrical connections to both the Coil over ignition coils and the passenger side fuel injectors. Once you remove the small bolt which holds the ignition coil in place, use your compressed air again to blow out the spark plug hole. After that, you will need a 5/8" swivel spark plug socket and various length extensions to remove the spark plugs. Take your time because there is not much room for your hands. Before installing the new plug, check the gap and use clean engine oil on the new threads. Tighten the new spark plug and reinstall the coil over ignition coil. Reconnect the electrical connection to both the ignition coil and the fuel injector. Continue these steps with all eight spark plugs. You will find the ones on the drivers side are difficult because of the fuel rail gets in your way. Have patience and use swivel extensions to work around the tight spaces. When you are done, you will have saved lots of money! Don't forget to replace your air filter, fuel filter, and pcv valve to complete your tune up.
