Standard Ignition AC29 Idle Air Control Valve

Idle Air Control Valve for Ford Thunderbird

Standard Ignition AC29 is an idle air control valve for 1987-1988 Ford Thunderbird applications. It is built to regulate bypass airflow at idle so the engine can maintain a stable idle speed under changing load conditions.

Key Features

• Idle Air Control Valve for fuel injection systems
• Uses a polymer-blended, isotropic neodymium/iron/boron magnet for precise pintle movement and airflow control
• High-strength stepping motor delivers strong output torque for accurate actuator response
• Shielded ball bearing helps resist environmental contaminants for longer service life
• Load-tested actuator for force output greater than actual load
• Manufactured with high-grade materials for durability and consistent performance

Detailed Description

Standard Ignition AC29 is engineered for 1987-1988 Ford Thunderbird idle control service and is also cross-referenced to select OE and aftermarket numbers for the same application. The AC29 uses a precision magnet and stepping-motor design to control the pintle and airflow with consistent movement, helping the engine management system maintain the correct idle strategy. This makes it a direct-fit service part for Ford Thunderbird idle air control valve replacement needs.

This part cross-references Walker Products 215-2004 for the same application.

What It Helps Address

• Unstable or fluctuating idle speed
• Idle speed that is too high or too low
• Stalling when coming to a stop
• Poor idle control after throttle release
• Idle quality issues related to airflow control at the throttle body

Installation Notes and Tips

Fits 1987-1988 Ford Thunderbird, N/A. Confirm the connector style, mounting points, and engine management calibration before installation. Clean the throttle body and adjacent air passages during service so the replacement idle air control valve can regulate airflow accurately. After installation, clear any stored idle-related fault codes and allow the engine to relearn idle strategy if required by the vehicle.

Quality Assurance

Standard Ignition manufactures this AC29 idle air control valve with high-grade materials and load-tested actuator components to support consistent operation and extended service life.
