I recently purchased a 2004 F150 xlt crew cab with the 5.4l engine in it. I really like the truck but have been experiencing a problem with the engine wanting to die at a light or while idleing. The rpm's go all the way down to about 200 while at a stop light and the truck is sluggish when you hit the gas. It only has about 60k miles on it. Any suggestions why it may be doing this? Thanks

Does anyone have any thoughts on this?
