You can go to most discount auto parts stores and they will read the code for you and tell you what that might indicate. If it is coils, and it might be, go to ebay and buy the whole set for $90 rather than the dealer where you will pay $00 each. Use the Ford plugs.

It may still have codes being stored but not enough to trip the CEL.
#20 of 20 Expedition that runs like crap by ktomlinson Nov 22, 2009 (5:34 pm)
I have a 2006 Expedition with a 5.4 in it. It started getting sluggish so I thought that it just needed plugs being it had 90,000 on it. That didn't fix it and the problem, which was no power, rough idle and bogging down, just gradually got worse. I decided to change the fuel filter and when I pulled it rusty water ran out of the filter. I thought for sure this was my problem so I pulled the tank and cleaned everything good. I put it back together and it still didn't fix it. It misses at idle, won't hardly pick up speed and when it does it will only go 40-45mph. The only code it has set is P0174 bank 2 running lean. I found the fuel pump was not putting up the pressure it should, changed that, and it still has not fixed it. Can someone please give me some insight on what it may be now. Thanks
