Welcome to the "B Zone"!
First thing you should try is doing a tune-up i.e. Plugs, Wires, Cap & Rotor, O2 Sensor, Fuel Filter & Air Filter.
If you are still having the problem then you should check the coil, EGR Valve and Vacuum lines

Since it is EFI and computer-controlled, I would scan for any codes. Alot of problems come from the IAC (Idle Air Control) valve and EGR (Exhaust Gas Recirculation). Also, check the timing on the motor.
