GM question....

Any free car is ok in my book. As far as any FWD POS, the GM models with the Buick 3.8 liter V6 are about the best running out there for reliability. The 94 up ( 97 up for the midsize and Camaros) models with the Gen II 3.8 are better

Your idle speed problem may be a sticking IAC motor, Your stang uses a similar stepper motor to control the idle speed, carbon builds up on the orifice and pintle valve. GM cars are easy to get codes out of the computer, you just jumper the top right two pins in the ALDL connector which is usually mounted ont the edge of the dash near the drivers seat, visiable pointing towards the driver. A KOEO test will flash the check engine light, code 12 is the handshake code followed by the trouble codes.
