Idles rough bad acceleration

When my car is in drive the rpms go up and down repeatedly and today it stalled on me. It also has delayed acceleration. It gets worse when the car is warm and running for a while. It seems like it is not getting air. Any ideas? No check engine lights. I had as miss fire and I thought that's what was causing this but i got that taken care of and it still is like this.

 
If it is your 02 RS then I'd say check your air filter, vacuum lines, and clean your idle air control valve and throttle body. If you pull a spark plug and it is black or really dark then you are running rich(not enough air or too much fuel). Might also be worth checking your MAP sensor and PCV valve.

Easy way to check vacuum lines= can of carb cleaner. Hose'er down from connection to connection, typically idle will race as the stuff gets sucked in through the leak. Might be worth getting a can of maf cleaner (idk if 02 had one) I found oiled air filters play hell with a mass air flow sensor, but sometimes they just get dirty.
