For the past three days, when I start my car in the morning, the RPM's dip real low and if I try to take off too soon the car acts like it's going to die. After that it seems to be okay. Anyone had a problem like this or know what this might be?

what kind of fuel you use? probably you use some kind of cheap fuel and it could clog your injectors therefore making your car acting funny at start.

I have the same problem.
At Startup the engine will idle very low, and run sort of weird. Its not the fuel since i have always but premium gas. Then about 5 minutes later it will be just fine.

You may want to test your Engine Coolant Temperature Sensor. This is easy enough, requiring only an ohmmeter.

On the 4th Generation Maxima engine the Engine Coolant Temperature Sensor is located in the water outlet tube close to the engine end of the upper radiator hose. There are two sensors in that area. The one nearest the hose is for the dashboard temperature gauge. The ECTS, the one you're interested in, is right next to the the gauge sending unit. There is a good picture of these sensors in the Haynes repair manual on page 3-7.

With the engine cold, disconnect the ECTS and measure its resistance.
Reconnect the ECTS, start the engine, run it until fully warmed up. Stop
the engine, and repeat the resistance measurement. The "warm" reading
should be a much lower value than the "cold" reading.

The manual gives these specs:
Engine coolant temperature 68F, ECTS resistance 2.1 - 2.9 Kohms
Engine coolant temperature 194F, ECTS resistance 0.24 - 0.26 Kohms
(Roughly a factor of ten difference.)

Sometimes its not available so I use 91. Maybe I'll run some injector cleaner through it or something.
