NewYall Idle Air Control Valve IACV for Dodge Jeep Chrysler — Direct-Fit Replacement, Restores Stable Idle

NewYall Idle Air Control Valve (IACV) restores stable idle performance for compatible Dodge, Jeep and Chrysler engines by precisely regulating intake airflow at low RPM.

If your vehicle experiences rough idling, stalling at stoplights, or inconsistent idle speed, the idle air control valve is a common service item. This NewYall replacement fits a range of late-model Dodge, Jeep and Chrysler V6 and V8 engines and is designed as a direct-fit aftermarket unit for models listed below. The part is built to match OEM mounting and electrical connections so installation is straightforward for a mechanic or a competent DIYer.

Which models and years will this IACV fit?

This NewYall IACV covers many Dodge, Jeep and Chrysler applications from the early to mid-2000s. Check your vehicle’s engine displacement and year to confirm compatibility before ordering.

• Dodge Dakota: 3.7L and 4.7L (2003–2007)
• Dodge Durango: 3.7L and 4.7L (2002–2007)

• Chrysler Aspen: 4.7L (2007)

How does this IACV improve idle and drivability?

The idle air control valve meters bypass air when the throttle is closed, allowing the engine management system to maintain a steady idle. A properly functioning IACV reduces surging, rough idling, and unintended stalls during warm-up or gear changes. Using a matched replacement helps the engine computer re-learn idle settings faster and more predictably.

• Regulates intake air for consistent idle speed
• Reduces rough idle and cold-start stalling
• Direct-fit design preserves OEM electrical and mounting interfaces

What should I know about installation and compatibility?

Installation typically requires hand tools, a clean mating surface, and basic electrical connector work. Always compare the replacement unit to the removed IACV to verify terminal count, shape, and gasket placement. If the vehicle has additional intake modifications or aftermarket engine management, consult a technician for compatibility.

• Direct-replacement; follow factory torque specs for mounting bolts
• Inspect and replace the O-ring or gasket if damaged
• Clear stored engine codes and allow the ECU to adapt after installation

How can I tell if the IACV is failing?

Failing IAC valves often produce telltale symptoms but may require diagnostic testing to confirm. If you notice idle irregularities, check-engine lights related to idle control, or inconsistent behavior at low speeds, the valve is a likely candidate. Cleaning sometimes helps, but a worn actuator or electrical fault usually means replacement is the reliable option.

• Symptoms include rough idle, stalling, and fluctuating RPM
• Diagnostic trouble codes and live-data tests help confirm failure
• Replacement recommended if cleaning doesn’t restore consistent operation

Who is this for: This NewYall IACV is aimed at owners and technicians repairing mid-2000s Dodge, Jeep and Chrysler vehicles listed above who need a direct-fit, cost-effective replacement for a faulty idle air control valve. It’s suitable for routine engine maintenance shops, independent mechanics, and experienced DIYers who confirm compatibility with their engine size and model year.
