Idling problems? Start with your IAC/ISC
Does your 3000GT or Stealth have a rough idle or die in neutral? The problem could be your idle air controller. Stealth316 has a useful guide on how to inspect and clean your ISC/IAC attached to the throttle body. I’ve done this on several cars with idling hesitation and 75% of the time it clears the problem up. All you need is some basic tools, electronics parts cleaner, and an hour or two of time. Be sure not to strip the screws or lose the spring inside the IAC.
