I don't know - bad motor mounts? Shouldn't be piston slap - that only happened on cold starts and they had solved that problem by end of '99, beginning of '00. I drive a V10, nice and smooth. Never noticed vibrations at idle in 5.4s that I've driven. My suggestion is make sure your keep good records of all the dealer visits -save all the receipts and service paperwork. This way if the engine self destructs at some later date, you may be able to get Ford to cover it under warranty since it was a reported problem during the original warranty period.

I had a 99 5.4 that I bought new. I had that exact problem -- they (Ford) tried everything you said, plus more. I decided to try the Ford Dispute settlement board. After 5-6 months and meeting (in person-- THIS IS IMPORTANT!) with the board, they bought my 99 back for my full purchase price minus a charge for mileage (calculated from the mileage at the time I first complained of the problem). Ford was shocked when they asked (off the record) what I planned to do-- I said buy another like f150/5.4. I did just that and the new (2002) does not have the same rough idle. I liked everything else about the truck. If you need more specifics on the process talk to your dealer (they are required by law, to tell you about the DSB) or email me at markmizzouhotmail.com.

My 2000 f150 5.4 does that soon after start up when the ambient temperature is above 60. Mentioned it to the dealer and he said,"it's not supposed to do that" but since he couldn't duplicate I'm SOL. I have to admit it's intermittent but I get 17 mpg so I guess I'll wait until it blows up. Pulls great and I still like the truck.

my father bought a new f150 in 87.after 5000 miles it developed a rough idle.during the warranty period the dealer replaced MANY items without luck.no one was able to resolve the problem after all these years.now i have this truck and it still idles rough especially when warm.it only has 71k on it and i have accepted the fact this 4.9 will never run smooth.a load of out of spec.mechanical parts dumped into one engine.some engines are destined to run rough.
