I'm new to working on cars but I figure now is the time to start learning about maintaining a car myself as opposed to taking my car into a dealer. I've been told that Integras (gen 3) should be tuned up at 90,000 miles. I'm just wondering, what exactly does a tune up include? Checking belts, timing, oil, fluids, brakes, etc? Also what tools are needed to perform a basic tune up? Any help would be appreciated. Thanks.
