Why is my Toyota RAV4 stalling?

Possible Causes of Toyota RAV4 Stalling
Based on the search results, there are several potential causes for a Toyota RAV4 stalling:
1. Bad Fuel Injectors: If the fuel injection system is allowing too much or too little fuel into the combustion chamber, or if it is not properly atomizing the fuel, the RAV4 may stall out.
2. Issues with Sensors: The RAV4 uses complex sensors to report information to the Engine Control Unit (ECU), which then adjusts various parameters. If one of these sensors malfunctions, it can lead to stalling.
3. Loose or Corroded Wires in Wiring Harness: Inconsistent firing of the ignition due to loose or corroded wires can result in an easily stalled engine.
4. Throttle Body Issues: Cleaning the throttle body may help resolve stalling issues. However, it is important to use throttle body cleaner and follow the proper procedure.
5. Engine Control Module (ECM) Defect: In some cases, a defective ECM can cause stalling. Toyota issued a technical alert in 2006 for a defective ECM in certain RAV4 models.
6. Idle Air Control Motor: The idle air control motor can become carboned up and cause stalling at idle or stop signs. Cleaning or replacing the motor, as well as cleaning the throttle body, may help resolve the issue.
It is important to note that these are potential causes and a proper diagnosis by a mechanic is recommended to accurately identify the specific cause of the stalling issue in a Toyota RAV4.
