Check trouble codes
On pre-1996 import cars, you use a wiring plug under the hood or access the computer to make the check engine light flash the codes.
You can do an internet search for "retrieve trouble codes" for your make and model for details.

Without actually inspecting/looking at the vehicle, the problem sounds like it's the Throttle position sensor (TPS). Before buying this component, you need to 'bench-test' it to be sure. The TPS is merely a potentiometer (variable resistor - POT) with center tap and two wiper plates (when the throttle is fully closed, the resistance in TPS A is at maximum and in TPS B is at minimum. When the throttle is wide open (W.O.T. - wide open throttle, the resistances of 'A' and 'B' circuits are opposite each other - A minimum and B maximum). The computer (Engine Control Unit - ECU) uses/monitors these signals to adjust/manage the fuel map (fuel trims). Using an analog Ohm Meter, you can test the TPS (or contact someone who knows how), to check for bad spots (erratic resistance changes) in the POT. If the POT is bad, you'll most probably find the problem where the POT is in/near the "IDLE" position... since that's where you mentioned sometimes 'stalls' when you hit the gas.
