Default Small Misfire

I'm looking into buying a 1999 Ranger with a 3.0 V6 Flex Fuel one thing I noticed is when the truck is parked and Idoling there is a small misfire or a noise the pops every once and while. Does anyone know what this is and does this lead to any other problems

you need the spark coming from the spark plug. if the wires or plugs aren't working and creating a spark then it misfires.
