What you likely need to do is address the underlying issue causing you to think a throttle body reset is necessary. Common symptoms that people *incorrectly* attribute to needing a throttle body reset include:
* Rough idle: This is often caused by vacuum leaks, dirty MAF sensor, failing ignition coils, or other problems.
* Hesitation or stumbling: Similar causes to rough idle, plus potential issues with fuel injectors or the fuel system.
* Check Engine Light (CEL): This indicates a diagnostic trouble code (DTC) stored in the PCM. You MUST get the code read using a OBD-II scanner to diagnose the actual problem.
What to do instead of a "throttle body reset":
1. Check for Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to read any codes stored in the PCM. This is the most crucial step. The codes will pinpoint the problem. Auto parts stores often offer free code reading services.
2. Clean the Mass Airflow (MAF) Sensor: A dirty MAF sensor is a very common cause of drivability issues. Carefully clean it with MAF sensor cleaner (available at auto parts stores). Do not touch the sensor element.
3. Inspect and clean the throttle body: While there's no reset, cleaning the throttle body can improve performance if it's dirty. Use throttle body cleaner and a clean rag, carefully cleaning the butterfly valve and surrounding area. Be careful not to damage the sensor.
4. Check for vacuum leaks: Inspect all vacuum hoses for cracks or leaks.
5. Check the battery: A weak or dying battery can cause erratic engine behavior.
Important Note: If you're experiencing significant drivability problems, simply cleaning the throttle body or MAF sensor won't solve the issue if there's a more serious problem. Ignoring a CEL and attempting a non-existent "reset" will not fix the underlying mechanical or electrical fault. A professional diagnosis is recommended if the problem persists after checking the above items.
