Service and Cost
Typical Cost
The cost to replace or repair the Intake Manifold Runner Control (IMRC) can vary based on several factors, including the make and model of the vehicle, the specific part that needs replacement, labor costs, and your location. Here's a general breakdown:
1. Part Cost: The cost of the IMRC part typically ranges from $75 to $450. OEM (Original Equipment Manufacturer) parts are usually on the higher end, while aftermarket parts are generally less expensive. OEM parts are often recommended for better compatibility and performance.
2. Labor Costs: At $125 per hour, labor typically takes 1.5 to 3 hours, resulting in labor costs between $187.50 to $375. The time variation depends on vehicle make and model, as some require more extensive disassembly than others.
3. Total Cost: Combining parts and labor, most IMRC replacements or repairs range from $262.50 to $825. Luxury or high-end vehicles may cost more due to specialized parts and additional labor requirements.
4. Additional Costs: If related components need repair or replacement (such as vacuum lines, electrical connections, or damaged intake manifold components), additional parts and labor will increase the total cost.
5. DIY Option: While DIY repair can save on labor costs, we recommend professional installation to ensure proper function and prevent potential issues. This repair requires specific tools and technical knowledge to complete correctly.
It's recommended to have a professional diagnosis performed, as IMRC symptoms can sometimes be confused with other engine management issues. We're happy to provide a detailed quote specific to your vehicle.
Typical Service Procedure
The Intake Manifold Runner Control (IMRC) system is an important component in many modern engines, designed to optimize airflow and improve engine performance and efficiency. When dealing with the replacement or repair of the IMRC, several key components and steps are typically involved:
1. Diagnosis: Before any repair or replacement, a thorough diagnosis is necessary. This involves using a diagnostic scanner to check for error codes related to the IMRC, such as P2004, P2005, or P2006, which indicate issues with the runner control system.
2. Intake Manifold Runner Control Valve: This is the primary component that may need replacement. The valve controls the opening and closing of the intake manifold runners. If it fails, it can cause performance issues and trigger the check engine light.
3. Actuator or Solenoid: The IMRC system often includes an actuator or solenoid that operates the runner control valves. If this component fails, it may need to be replaced to restore proper function.
4. Linkages and Bushings: The mechanical linkages and bushings that connect the actuator to the runner valves can wear out or break. These parts may need to be replaced to ensure smooth operation.
5. Gaskets and Seals: When replacing parts of the IMRC system, it is often necessary to replace gaskets and seals to prevent air leaks and ensure proper sealing of the intake manifold.
6. Cleaning: Carbon buildup can affect the operation of the IMRC system. Cleaning the intake manifold and related components may be part of the repair process to ensure optimal airflow.
7. Reprogramming or Calibration: After replacing components, some vehicles may require reprogramming or calibration of the engine control module (ECM) to ensure the new parts function correctly with the existing system.
8. Testing: Once repairs are completed, the system should be tested to ensure that the IMRC is functioning properly and that any error codes have been resolved.
9. Labor: The complexity of accessing and replacing the IMRC components can vary significantly depending on the vehicle make and model, affecting the labor cost and time required for the repair.
Our experienced technicians can provide specific procedures and recommendations related to your vehicle's IMRC system repair needs.
What is an Intake Manifold Runner Control and What Does It Do?
The Intake Manifold Runner Control (IMRC) is a component in some internal combustion engines that helps optimize the air-fuel mixture entering the engine's cylinders. It is part of the intake manifold system, which is responsible for distributing air to the engine's cylinders.
The primary function of the IMRC is to adjust the path and flow of air entering the engine based on the engine's speed and load conditions. It typically consists of a set of valves or flaps located within the intake manifold runners. These valves can open or close to change the length and path of the air intake runners.Here's how it works:
1. Low RPM/Load Conditions: At lower engine speeds and loads, the IMRC system may close certain valves to create a longer, more restrictive path for the incoming air. This helps increase air velocity, which improves the mixing of air and fuel, leading to better combustion efficiency and torque.
2. High RPM/Load Conditions: At higher engine speeds and loads, the IMRC system opens the valves to allow a shorter, less restrictive path for the air. This maximizes airflow into the engine, which is beneficial for producing more power.
By adjusting the airflow characteristics, the IMRC system helps improve engine performance, fuel efficiency, and emissions across a range of operating conditions. It is controlled by the engine's electronic control unit (ECU), which uses input from various sensors to determine the optimal position of the IMRC valves.
Signs of a bad Intake Manifold Runner Control
The Intake Manifold Runner Control (IMRC) system is responsible for optimizing the air-fuel mixture entering the engine by adjusting the length of the intake manifold runners. This system can improve engine performance, fuel efficiency, and emissions. When the IMRC system or its components fail, it can lead to various symptoms. Here are some common signs of failure:
1. Check Engine Light (CEL): One of the most common indicators of a problem with the IMRC is the illumination of the check engine light. Diagnostic trouble codes (DTCs) related to the IMRC, such as P2004, P2005, P2006, or P2007, may be stored in the vehicle's computer.
2. Reduced Engine Performance: A failing IMRC can lead to a noticeable decrease in engine performance, especially at certain RPM ranges. This is because the system is unable to optimize the air-fuel mixture effectively.
3. Poor Fuel Economy: If the IMRC is not functioning correctly, the engine may not run as efficiently, leading to increased fuel consumption.
4. Rough Idle: A malfunctioning IMRC can cause the engine to idle roughly or inconsistently, as the air-fuel mixture may not be properly balanced.
5. Engine Stalling: In some cases, a faulty IMRC can cause the engine to stall, particularly when coming to a stop or when the engine is idling.
6. Hesitation or Misfiring: The engine may hesitate or misfire during acceleration if the IMRC is not operating correctly, as the air intake may not be optimized for the engine's needs.
7. Unusual Noises: You might hear rattling or other unusual noises coming from the engine bay, which could indicate that the IMRC components, such as the actuator or linkage, are worn or damaged.
8. Failed Emissions Test: A malfunctioning IMRC can lead to increased emissions, potentially causing the vehicle to fail an emissions test.If you suspect an issue with the IMRC, it's important to have the vehicle diagnosed and repaired by a qualified technician. They can use diagnostic tools to read any stored trouble codes and perform tests to determine the exact cause of the problem.
