1. Gather your supplies:
* Throttle body cleaner: Use a specific throttle body cleaner, *not* general purpose carb cleaner. Carb cleaner can damage sensors. Look for a product designed for throttle bodies and fuel injection systems.
* Shop rags or clean cloths: You'll need several to wipe things down.
* Screwdriver (likely a Phillips head): To remove the air intake tube.
* Socket wrench and sockets (possibly): Depending on your specific Ranger, some intake components might require a socket.
* Protective eyewear: Throttle body cleaner is harsh and can damage your eyes.
* Gloves: To protect your hands.
* Optional: Small brush: A toothbrush or similar small brush can help get into crevices.
2. Disconnect the battery: This is a crucial safety step to prevent accidental short circuits. Disconnect the negative (-) terminal first.
3. Remove the air intake system:
* Locate the air intake tube connecting to the throttle body.
* Remove the clamps holding the air intake tube in place. These are usually hose clamps, and you might need a screwdriver to loosen them. There might be a MAF sensor (Mass Air Flow sensor) on this tube. Be careful not to touch the sensor element (usually a hot wire or thin film) on the MAF; oil from your fingers can ruin it.
* Disconnect the air intake tube from the throttle body.
4. Access the throttle body: You should now have a clear view of the throttle body.
5. Clean the throttle body:
* Spray liberally: Apply the throttle body cleaner according to the product's instructions. Focus on the throttle plate and the surrounding areas. Let it soak for a few minutes.
* Use a brush (optional): Gently scrub away any stubborn deposits with the brush, being careful not to damage any delicate parts.
* Wipe clean: Thoroughly wipe down the throttle body with clean cloths until all the residue is removed. Ensure the throttle plate moves freely.
6. Reassemble:
* Reattach the air intake tube and secure the clamps.
* Reconnect the battery.
7. Start the engine: Let the engine run for a few minutes to allow the engine computer to re-learn the idle. You might experience a slightly rough idle for a short period.
Important Considerations:
* Safety First: Always wear eye protection and gloves. Work in a well-ventilated area.
* Don't Overspray: Avoid spraying the cleaner directly onto any sensors.
* Throttle Plate Movement: Make sure the throttle plate moves freely after cleaning. If it's stuck, you might need to manually work it open and closed gently several times.
* MAF Sensor Cleaning: If your MAF sensor looks dirty, you can carefully clean it with MAF sensor cleaner (a different product from throttle body cleaner; don't use throttle body cleaner on the MAF!).
* If Unsure, Seek Professional Help: If you are uncomfortable performing this task, it's best to take your vehicle to a qualified mechanic.
This guide provides general instructions. The specific procedures might vary slightly depending on your particular 2000 Ford Ranger 3.0 V6. Consulting a repair manual specific to your vehicle is always recommended for detailed instructions and diagrams. You can often find these manuals online or at auto parts stores.
