My '97 3.8 'vert used to have a tough problem - it was a little hard to start, idled roughly at 400 rpm, and pressing the gas pedal would kill it unless you were very gentle. I had probed the MAF signal and it seems to be fine. I was about to probe the TPS sensor signal... And then I had the genius whim to see if unplugging the ICV would change the idle. Yeah, it did. Instantly, the car died. I heard a faint pop. All the dash lights went out. Turning the key doesn't produce any response at all - no dash lights come on, no turn over, no nothing. I checked the fuses in the underhood fusebox and they're all okay. Anybody got any idea what I killed?
