5. Nastavení a instalace
Professional installation is highly recommended for this component due to the complexity of modern engine systems and the need for precise calibration. No specific installation instructions are included with the product.
If you are performing the installation yourself, please consider the following general guidelines:
- Bezpečnost především: Disconnect the vehicle's battery before beginning any work. Ensure the engine is cool.
- Locate the Throttle Body: Těleso škrticí klapky se obvykle nachází mezi hadicí sání vzduchu a sacím potrubím.
- Odpojení komponent: Carefully disconnect the air intake hose, electrical connectors, and any coolant lines or vacuum hoses attached to the old throttle body.
- Odstraňte staré tělo škrticí klapky: Unbolt the old throttle body from the intake manifold.
- Nainstalujte novou škrticí klapku: Mount the new MXR throttle body, ensuring a proper seal with a new gasket (if required and not included).
- Znovu připojte komponenty: Reattach all electrical connectors, coolant lines, vacuum hoses, and the air intake hose.
- Znovu připojte baterii: Znovu připojte baterii vozidla.
- Calibration/Relearn Procedure: Many modern vehicles require a throttle body relearn procedure after replacement. This often involves specific steps (e.g., turning the ignition on/off, pressing the accelerator) or may require a diagnostic scan tool. Consult your vehicle's service manual or a professional for the exact procedure.
Důležitá poznámka: This throttle body is designed to fit aftermarket intake manifolds that are larger than stock size. If using a stock-sized intake manifold, a spacer may be needed to allow the throttle plate to fully open.

6. Principy fungování
The electronic throttle body works in conjunction with your vehicle's Engine Control Unit (ECU). When you press the accelerator pedal, it sends an electronic signal to the ECU, which then commands the throttle body's electric motor to open or close the throttle plate. This precisely regulates the amount of air entering the engine, which is then mixed with fuel for combustion. This electronic control allows for more accurate and responsive engine management compared to older cable-driven systems.

7. Údržba
Regular maintenance of your throttle body can help ensure optimal engine performance. Over time, carbon deposits and grime can build up on the throttle plate and inside the bore, affecting its operation.
Cleaning the Throttle Body
It is recommended to have the throttle body inspected and cleaned periodically, typically during routine vehicle maintenance. A professional technician can safely clean the throttle body using specialized cleaners without damaging sensitive electronic components.
Caution: Improper cleaning methods or harsh chemicals can damage the electronic components of the throttle body. Always consult a professional or your vehicle's service manual for recommended cleaning procedures.
8. Řešení problémů
If you experience any of the following symptoms, your throttle body may be malfunctioning or damaged:
- Obtížnost při startování: The vehicle struggles to start or fails to start.
- Throttle Not Returning: After pressing the accelerator, the throttle does not return to its idle position.
- Increased Smoke and Fuel Consumption: Noticeable increase in exhaust smoke and/or a significant drop in fuel economy.
- High Idle Speed: The engine idles at an unusually high RPM.
- Uneven Acceleration: Hesitation or surging during acceleration.
If these issues occur, it is advisable to have your vehicle inspected by a qualified mechanic to diagnose the problem and determine if the throttle body requires replacement or repair.

9. Uživatelské tipy
I když žádný konkrétní uživatel neviews or Q&A were available for direct inclusion, general tips for throttle body replacement and maintenance include:
