Detailed Description

The Standard Ignition AC420 idle air control valve is engineered to regulate bypass air around the throttle plate so the engine can maintain a stable idle under changing load conditions. Its motor and magnet design support accurate pintle movement, while the sealed bearing construction helps extend service life in demanding underhood environments. This part cross-references Delphi CV10162 for the same application.

What It Helps Fix

• Rough or unstable idle speed
• Stalling when coming to a stop
• Idle fluctuation during accessory load changes
• Hard starting caused by poor idle air control
• Idle quality issues on Chrysler Sebring, Dodge Stratus, and Jeep Wrangler models

Installation Notes and Tips

Verify throttle body condition before installation and clean any carbon buildup from the air bypass passage. Confirm the connector style, 4-terminal layout, and 1-port configuration match the original part before replacement. Use the included gasket and hardware during installation, and clear any stored idle-related diagnostic trouble codes after service.
