Idling problems? Start with your ISC
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 a Sunday afternoon. Be sure not to strip the screws or lose the spring.
