Where is the idle air control valve on a Lincoln towne car 1991?

On a 1991 Lincoln Town Car, the Idle Air Control (IAC) valve is typically located on the throttle body. The throttle body itself is usually found on the intake manifold, near the engine's front. It's a relatively small, cylindrical component with electrical connectors.

However, precise location can vary slightly depending on the engine (4.6L or 5.0L). The best way to locate it definitively is to:

1. Consult your 1991 Lincoln Town Car's repair manual: This will have diagrams and detailed descriptions of the engine compartment.

2. Use a repair manual app or online resource: Many online resources, such as Mitchell OnDemand or AllData, contain detailed diagrams for various vehicle makes and models. (Note that these often require a subscription).

3. Search online for "1991 Lincoln Town Car IAC valve location" + your specific engine size: Images from others who've worked on similar vehicles may help.

Remember to be cautious when working near the engine; it may still be hot. Always disconnect the negative battery terminal before starting any work on the electrical system.
