What is the location of idle speed adjustment screw on a 1988 Mercury Tracer?

The idle speed adjustment screw on a 1988 Mercury Tracer (which uses a Ford engine) is typically located on the throttle body. However, its exact location and accessibility can vary slightly depending on the specific engine (1.6L or 2.3L).

You'll likely find it on the side of the throttle body, often near the linkage connecting the throttle cable to the throttle plate. It's usually a small screw with a slotted head. It might be somewhat hidden, so you may need a small flashlight and possibly some maneuvering to see it clearly.

Important Note: Before adjusting the idle speed screw, be sure to consult your owner's manual or a repair manual specific to your 1988 Mercury Tracer's engine. Incorrect adjustment can negatively affect the engine's performance and fuel efficiency. Also, be aware that many newer vehicles have electronic throttle control, which eliminates a manually adjustable idle screw. While possible, it's less likely on a '88 Tracer.
