Engine miss

So I have a #1 cylinder misfire(code301) and a bank one lean (171), I changed plugs, wires, what else can it be? I dont think it is the coil because it is only on #1 cylinder, could the injector be clogged? When I start it up it does not miss, only after it warms up. So I figure since it is on fast idle it is runnin rich that is why it doesnt miss. Anyone have any ides? Oh yeah, it is 01, 4.0L.
