Question about Ford Cars & Trucks
Changed crossed wires now the engine power is lessening
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.

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.

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.

Good Evening, the oil filter on the 4.6l if you are underneath just to the drivers side passed the pulleys and such if you look up to the engine block you will see it. Hope this helps.
