Hey guys wanted to get your opinions. I have a 98 Eddie Bauer Expedition with a 5.4L in it. Changed the oil, fuel filter (HAD JIFFY LUBE DO THIS FOR ME), and recharged the A/C system and after starting it up and letting it run it idled rough. When I took it for a drive it was vibrating when I gave it gas almost like a miss. I bought some new plugs for it today and going to install them, I also bought a new IAC. Anything else you think it could be?

spark plug boot - most likely #3 or #4 cyl.

Does it matter it's coil on plug? I would throw a code for a mis-fire
