Okay let's regroup for a minute. You can mist the wires with water and see if it acts up to see if it is a moisture issue, and if you replace the wires, then yes do the boots.
I just want to review a minute, You just mentioned a starting problem, is it cranking a long time to start?
Codes po300 and po171 are still present.
The lack of power is still present. Does that lack of power change once it is warmed up or not matter if it is cold or warmed up?
Was the fuel pressure good?
Are you in a cold climate? There was a recall on the altimas for a small screen between the pump and sock that would freeze up and prevent flow.
(can call the dealer service dept. With your vin to see if any outstanding recalls are not done)
//Going after the multple misfire code from the research I have just done suggests pulling the plugs when the engine is cold and pressure testing the coolant for seapage of coolant going into the cylinders.
HAve you had to add ANY coolant?
Are there any pools of oil in any of the spark plug holes?
Did you do anything with that front O2 sensor?
