If the check engine light is on (from the misfire from the crossed wires), the computer is in "reduced power" mode. You need to clear the codes with a scan tool and try again.

If you clear your MIL Lamp--you loose all your freeze frame
data,at the time the fault codes are set,need that Mode $06 Data

I never clear any data-- even after a repair

Let the Emission Monitors run first & road test & look at data

Unless you have a Class A Cylinder Misfire-- I don't know if your
going into failsafe on a 1999 ford --on a newer CAN Vehicle- yes

SOURCE: engine code p0307 cylinder #7 misfire

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

SOURCE: how to change spark plugs on a ford expedition

I recently changed them and it was a job when you have to crawl up and inside the engine area. But anyways, I started out by buying the E3 plugs, which don't have to be gapped and they do save a little gas plus increased in a little more power. (not much), These set me back $56. go with a basic motorcraft platinum or bosch platinum. I then removed the top engine cover, removed bolts for fuel rail and easily pulled the injector rail up (you will see to replace the o-rings on the injectors by some people, but if you're careful you don't have to.) This gives you the room you need at the back of the engine to remove the plugs. I started at the front by removing the small bolt holding the coil in place, then removing the the coil/wire with a boot removal tool. ( Again you don't need this tool, but it comes in handy at the back plugs). After removing the coil, I simply remove the plug, Apply anti-seize to the new one and install plug. I then apply Di-Electric grease to the inside of the coil boot to prevent moisture getting in. I then install the coil back down on the plug and tighten down and move on to the next.
1. you will need a swivel for the socket
2. you will need an extension, ( I use a long 8" extension)
3. Anti-Seize Grease
4. Di-Electric Grease
5. If installing a plug to be gapped it is .54
6. After installing, check for fuel leaks at the injectors.

It took me about 1 1/2 hours to replace all plugs and a dealer charges about $375. Good Luck if you need any further help get back to me and I'll help any I can.

I have just completed a tune up on my 1998 Ford Expedition 4.6 L V8 and the truck is backfiring and I can nor find the problem. I have the feeling that I crossed a wire and I cant figure out which on. ...


it definitely sounds like that you have a wire ,or wires crossed on the distributor cap, the firing order should be on the intake manifold, the best way to see what the direction of fire is , is to remove the distributor cap, and have someone crank over the engine, to see what direction the rotor is turning, then after cap is put back on, look for the #1 firing position on the cap, this will be # 1 plug wire, then you will have to continue onward following in the direction that the rotor turned, on the cap, following the firing order, 1 plug wire at a time.

HOW TO CHANGE COIL PACK ON 2000 FORD EXPEDITION EB 5.4 ENGINE?


Ther is no coil "PACK" on your engine. Each plug has its own coil. Each one is held in place by a single 8mm head bolt that screws into the intake plenum. To change them you simply disconnect the electrical connector, remove the bolt and pull the coil and spark plug boot up out of the spark plug tube. (Reverse proceedure to install.)

Looking at the truck with the hood open, far left, behind electrical wires...hard to see on 5.4L V8 engines. Best to find it when the engine is completely cold, 1st thing in the morning usually. IT will be hard to see, but it is there. Close to the engine oil fill cap.
