Does it change on the front when you move the temp control. Its likely if the expansion valve has been replaced that the blend door isn't closing all the way and some air is going thru the heater core.
check your radiator if theres a bubbles while your engine runnin, if theres bubble, it means you overheat. check your cylinder head for warps... also check your fans...
There is no carburetor on your car, it is fuel injected. Your coil is what fires the ignition. You can buy a Haynes manual, which has a troubleshooting section in it, but it sounds to me like you aren't really too sure around cars, so i'm going to suggest you find a reputable mechanic to take the car to. It may be a simple problem, but if you aren't comfortable working on cars, the mechanic is the best route. i'm sorry not to be of more help, but problems like this one can be caused by a variety of things only diagnosable while with the car to test as you go.
On a Fixed Orfice Tube system (FOT) the compressor cycles on and off because there is no other way to regulate the refrigerant. On a Thermal Expansion Valve system (which is what Nissan uses) the compressor stay on because the expansion valve regulates the refrigerant. It is not normal for your compressor to cycle on and off. Check your refrigerant level.

Thank you for choosing FixYa.com for your answer I am David
You changed sparkplugs and wires and the timing is good you say well there is a whole list of things that could be causing your troubles such as pcv valve, air filter,fuel filter,etc
Before you put alot of money into changing everypart on a typical fault check list my advice
is to take it to a local dealer or garage and have it hooked oon there computer for a more detailed
answer in the long run its cheaper that way.Again thank you for choosing Fixya.com
Make sure the PVC system is not plugged or disconnected, this causes pressure in the crankcase and hence the oil in the air cleaner, seen it many times
