I got a 99 expedition with the 5.4, My problem is when I start the truck when it's cold I have a misfire until the engine is at normal operating temp.
I changed the plugs ( motorcraft sp-479) and coils ( ebay from uneek) last month. it ran fine till last week.
the check engine light came on and gave a misfie on cyl. #5, I changed the coil and still the same. Any ideas or suggextions?
Thanks
