Noise and/or failure of the variable cam timing phasers is a well known issue on the 5.4L V-8. In 2006, Ford issued a technical service bulletin, denoted TSB 06-19-8, to explain the service and repair procedures to deal with the noise.
Typically, worn phasers create a loud and rough idle (also stalling). Often, a knocking noise is heard. In some instances, the noise is not due to wear in the phasers but rather low oil pressure due to cam bearing wear in the cylinder heads. If that is the case, the heads may need to be replaced or machined.
See the TSB for specific instructions but additional reported fixes have included installing a high volume oil pump.
Glenn, I'm sorry to hear about all of your problems. I just read through the entire thread. Part of the problem is probably Cam Phasers. They are locked at idle by pins operated by the solenoids (that you already had replaced) oil pressure operated the cam phasers and the biggest issue is keeping them lubricated at idle because the oil pump isn't a high pressure pump. Once the engine comes above idle the solenoids pull the pins and then computer determines whether to advance or retard the timing as needed. (this explains why it works better at higher speeds.This is exactly what it's doing. I get some laboring around 40mph, and stalling when stopping. He's trying the cheap repairs first before jumping right into the timing chain. It's only at 188k so with luck I can shove off the timing chain work until later. Fingers crossed.

I don't know that I would say it was "shot", but if anything under the front engine cover is and, you should replace all the components ! Cam phaser, timing chain, chain guides, tensioners and the oil pump (pay the up charge for a Melling high volume oil pump).My personal opinion is that an engine that has 180,000 miles on it is shot.
The parts are about $110 each on rockauto.com and from what I've seen they aren't too difficult to change.I took it to a Ford dealer this morning. The tech said he has to replace two more solenoids. $650. Ouch. Fingers crossed - I have to get lucky at some point. Dropping a new engine in the thing is at least $5000, and I just don't have that.

Chris, my 05 was going strong at 146,000 miles with a slight tick at idle. I never had the marbles in a can noise. I think your experience was atypical not the norm. There are a lot of 05 guys that have had minimal problems. It sounds like you just got a bad one.Hello Glenn,
I wouldn't waste the money if I were you on this truck. I had an 05 with constant cam phaser issues. Many trips to the dealership to resolve under warranty until I got tired of dealing with it and Ford must have too because they posted a TSB saying it was normal to hear marbles in a tin can coming from the engine at 1200 to 1800 RPM. Then it would stall or rough idle whenever it felt like it. So I did the smart thing after that..I disconnected the right bank to eliminate the phasers...ignored the check engine light...went back to a 1st gen expy...and traded the 05 for an 09 CTS. Save yourself the pain.
