My 2006 FX35 randomly has to crank for a longtime before it will start, it has 36K miles on it.

I bought it one month ago and do not know how old is the battery, spark plugs and air filter. This problem happened 3 times since I bought it, I think I have started it for 50 times so far. This baby runs great, very powerful like the new 2010 Infiniti FX35 I drive, sometimes I feel it's more powerful then the new FX35. There is a top model Compustar remote start and alert system installed on it, I tried to remote start the car four times, it works great, the engine started right away. I found a video on youtube shows exactly the same problem with mine, at least the sound is exactly the same. I am new to here so I can't post any link, please search youtube by " 2006 FX35 hard start no check engine lights.mp4 " for details.

Your comments would be highly appreciated!
 
Fixed!

Haha! This is my first time to fix a car, I spent 3 hours to do that, but about half of the time I used to pick up all kinds of things like screwdrivers, screws and pliers that I dropped into the engine compartment.
What I did is: I replaced the air filter with a K&N one. I cleaned the air intake box. I cleaned the throttle body with throttle cleaner. After that, the engine starts very good so far, the hard start has gone. But I found the gas consumption was around 30L/100KM, I realized there is something wrong with the computer. So I performed the "learning"s.After that, the gas consumption reads normal. RPM reads 700, more powerful driving, Done!!
Next time I should be able to do it in 30mins.
