Running rough...

I have a 92 325is e36 and i drove it the other day and it almost sounds like a Harley. I replaced fuel pump and battery. When the car is cold it starts up ok, but when car is warm it wont hardly start at all unless it cools down, and when I am at a stop light it will idle between 700 to a 1000. when you first press the gas it sputters until it hits 2k then the car is great. i have no check engine light on at all? should i still run the stomp test?

Yes, your car will tell you what is wrong with it if a sensor is not giving out the proper signals. Take a look at my article on reading fuel injection fault codes in the tech articles section, and that should give you a good clue where to start.
