Idle Air Control Valve for Ford Tempo and Mercury Topaz
Standard Ignition AC35 is an idle air control valve built for precise airflow management during changing engine load conditions. It is a direct-fit fuel injection system component for select Ford Tempo and Mercury Topaz applications, with 2 blade terminals for straightforward electrical connection.
- Precision-machined housing helps maintain proper air flow as commanded by the ECU
- Solenoid components are machined for consistent magnetic actuation of the plunger
- High-temperature polyester-coated coil wire supports operation during repeated heat exposure
- 2-terminal design with blade terminals
- Fits 1992-1994 Ford Tempo and 1990-1994 Mercury Topaz applications
Application Details
This idle air control valve is engineered for vehicles that need stable idle speed control when engine load changes, such as when accessories engage or operating conditions shift. Standard Ignition AC35 is a fitment-based replacement for 1992-1994 Ford Tempo and 1990-1994 Mercury Topaz models, and it cross-references Four Seasons 76222 for the same application.
Common Problems It Can Address
- Unstable or fluctuating idle speed
- Idle speed that is too high or too low
- Stalling when coming to a stop
- Idle quality issues after load changes
- Driveability concerns related to air bypass control
Installation Notes
Verify connector style before installation; this unit uses 2 blade terminals. Clean the throttle body and related air passages before replacing the valve, and confirm the vehicle application matches the listed Ford Tempo or Mercury Topaz fitment. Follow factory service procedures for idle relearn or ECU reset steps if required by the vehicle.
Quality Assurance
Standard Ignition manufactures emission-related components with in-process quality control from component production through final assembly. The AC35 uses a precision-machined housing and solenoid assembly, along with heat-resistant coil wire, to support consistent operation in demanding underhood conditions.
