My car rev's up and down while in park, and when driving, at a stop light it still rev's up & down like it's going to turn off. What could be the problem

I believe your car is surging. If you are saying that it does this all the time except when you touch the accelerator with your foot, ask yourself if you have had any work done to the intake manifold. I would check the vacuum hoses, coolant level, purge the cooling system of air in the system.
