I have a 2003 Nissan Frontier 4X4 6 cylinder truck. I keep getting a misfire in cylinder 2. This only happens when the engine has ran for 15+ mins or so, turned off for 5 mins, then I start it up again. The engine rumbles pretty bad for a few mins then it is fine again. I have changed the spark plugs/ wires, rotor/cap, oil and the fuel filter. Kinda stumped on this one. Any thoughts?

You also need fuel and compression. Since this is intermittent, compression and valve problems are not good suspects. Consider switching two injectors to see if the diagnostic fault code switches to a different cylinder.
