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.
