Wow.... Now She Goes
Since I've got my 5.4 L, 05 Scab F-150 a few months ago, I've never been happy with the performance of the truck; as it would seem some others here have also mentioned this. I've also had on two occasions "service engine" faults light up. So after a couple of trips back to my dealer they resolved my heart ache.
So boys, the scoop is......... new plugs..... yup, there's a new set with different numbers. I don't know the exact type, but it's in Ford's service tech's system.
Also, there's an update for the on board computer.
The truck is MUCH more responsive, it down shifts sooner, and harder. Acceleration is way up.
It even sounds better, and rev's up faster.
I'm not implying this affects all the 2005 5.4's, this is based strictly on my truck build, with pre-existing issues.
Hope this may help others with similar issues.

I had mye truck CPU reflashed and still have some performance problems but not as bad. what is the part nubmer of the new plugs. Some be on your paper work from the dealer. I think if you could post that info, would be a great info for everyone to make their truck better.
Well......it's been over a week since the new plugs and flash update were done, and I couldn't be happier. For me and my truck, this was a Must Do.
Has anyone else done the plugs and re-flash??????
gandnb,
Sorry, nothing on my Ford paperwork gives the new plug type used. But it should be a no charge warranty issue; so I'd bring her in for a free-bee plug swap and a re-flash to the latest version.
billc,
I wouldn't know if this service bulletin also applies to the 4.6's

just got a brand new 05 3 days ago w/ the 5.4, sales guy said he didn't know about any service bulletins, next time i'm at the dealer i'm asking the service tech. the tranny does feel slow to shift....
All this is well and good guys but we need a reason for the reflash and plug swap. The dealer isn't going to perform these services just because we tell them we want them done. Even if we give them the symptoms they aren't gonna do the work unless they find the symptoms, and even if we are having problems they are going to do work according to what they find wrong. So even if we want a plug swap we might not get it!!
A service rep told me it was an injector problem, when they fixed the injector they would replace the spark plug? We just need to keep pooling our info, I don't think any one person will get a complete or full answer to any problem.
