OEM Fuel Injection Throttle Body for 2009-2015 Cadillac, Chevrolet, GMC, Hummer, & Saab

Before you buy a replacement throttle body, consider these points:

• Compatibility: Even though this part fits many vehicles, double-check that it's the correct one for your specific year, make, and model.
• Condition: Decide whether you want a used, refurbished, or new aftermarket part.
• Warranty: Look for a part with a warranty to protect your investment.
• Seller Reputation: Buy from a reputable seller with good reviews.

Quality Indicators:

• Cleanliness: A clean throttle body is a good sign of proper care and maintenance.
• Smooth Operation: The throttle plate should move smoothly and freely (if applicable to your model).
• Proper Testing: Ask the seller if the part has been tested to ensure it's working correctly.

What's Included:

Typically, the throttle body comes as a complete unit. You may need to reuse your existing gaskets or purchase new ones separately. Check with the seller to confirm what's included.

Replacing a throttle body is a moderately difficult task that can be done at home with the right tools and knowledge.

• Difficulty Level: Medium
• Estimated Time: 1-2 hours

Special Tools Needed:

2. Remove the Air Intake: Disconnect the air intake hose and any other components attached to the throttle body.
3. Disconnect Electrical Connectors: Carefully disconnect the electrical connectors from the throttle body.
4. Remove the Throttle Body: Unbolt the throttle body from the intake manifold.
5. Clean the Mounting Surface: Clean the mounting surface on the intake manifold to ensure a good seal.
6. Install the New Throttle Body: Install the new throttle body and tighten the bolts to the correct torque specification.
7. Reconnect Electrical Connectors: Reconnect the electrical connectors.
8. Reinstall the Air Intake: Reinstall the air intake hose and any other components.
9. Reconnect the Battery: Reconnect the battery.

DIY or Professional Installation?

If you're comfortable working on cars and have the necessary tools, you can probably replace the throttle body yourself. However, if you're not confident, it's best to have a professional do it.

Here's a look at the different options available when buying a replacement throttle body:

• Used OEM: These are genuine factory parts that have been removed from used vehicles. They offer the best value, as they are tested and inspected to ensure they are in good working condition, but cost less than other options.
• Refurbished OEM: These are factory parts that have been professionally restored with new components. They are a good option if you want a part that's like new but don't want to pay the price of a new part.
• New Aftermarket: These are brand new parts that are manufactured by third-party companies. They are built to meet or exceed OE specifications and are a good option if you want a new part at a competitive price.

When replacing the throttle body, consider replacing or checking these related parts:

• Throttle Position Sensor (TPS): This sensor tells the car's computer the position of the throttle plate. If it's faulty, it can cause similar symptoms to a bad throttle body.
• Idle Air Control (IAC) Valve: This valve controls the amount of air that bypasses the throttle plate at idle. If it's clogged or faulty, it can cause rough idling or stalling.
• Air Filter: A dirty air filter can restrict airflow and cause the throttle body to get dirty more quickly.
• Intake Manifold Gasket: This gasket seals the intake manifold to the engine. If it's leaking, it can cause vacuum leaks and affect engine performance.

Replacing these parts at the same time can prevent repeat failures and ensure that your car runs smoothly.

A fuel injection throttle body typically lasts for 100,000 to 150,000 miles.

Factors that affect longevity:

• Driving Conditions: Stop-and-go driving can cause the throttle body to get dirty more quickly.
• Maintenance: Regular cleaning of the throttle body can extend its lifespan.
• Air Filter: A clean air filter helps prevent dirt and debris from entering the throttle body.
• Fuel Quality: Using high-quality fuel can help prevent carbon buildup.

The cost of a replacement throttle body can vary depending on the type of part (used, refurbished, or new aftermarket) and the brand.

• Budget: $50 - $150
• Mid-Range: $150 - $300
• Premium: $300 - $500+

Labor costs to install a throttle body typically range from $100 to $300, depending on the mechanic's hourly rate and the complexity of the job.

Total job cost estimates:

• Budget: $150 - $450
• Mid-Range: $250 - $600
• Premium: $400 - $800+

Some Cadillac, Chevrolet, GMC, Hummer, and Saab vehicles are known to experience throttle body issues due to carbon buildup. Regular cleaning can help prevent these problems. Some models may also be more prone to TPS failure, which can mimic throttle body problems. Check for any Technical Service Bulletins (TSBs) related to throttle body issues for your specific vehicle.

After installing the new throttle body, verify that it's working correctly:

• Start the Engine: The engine should start smoothly and idle properly.
• Check for Trouble Codes: Use a scan tool to check for any new trouble codes.
• Listen for Unusual Noises: There should be no unusual noises coming from the throttle body area.
• Test Drive: Take the car for a test drive to ensure that it accelerates smoothly and doesn't stall.
• Monitor Idle Speed: Ensure the idle speed is within the manufacturer's specifications.

If you notice any problems, double-check your work and consult a professional mechanic if needed.

Q: How often should I clean my throttle body?
A: It's recommended to clean your throttle body every 30,000 to 50,000 miles, or more often if you drive in dusty conditions.

Q: Can a dirty throttle body cause my car to fail an emissions test?
A: Yes, a dirty throttle body can cause your car to fail an emissions test due to increased emissions.

Q: Will a new throttle body improve my gas mileage?
A: Yes, a new or cleaned throttle body can improve your gas mileage by restoring proper airflow to the engine.

Q: Do I need to reset the car's computer after replacing the throttle body?
A: Yes, it's recommended to reset the car's computer after replacing the throttle body to allow it to relearn the new settings.

Q: What happens if I don't replace a bad throttle body?
A: Ignoring a bad throttle body can lead to poor engine performance, stalling, and eventually, potential damage to other engine components.
