The Toyota Rav 4 has a completely computer-controlled carburation step that prevents the slothful from life adjusted manually. When you are satisfied, shut off the engine.
Instructions
1. Remove the air cleaner from the top of the Toyota Rav 4 engine with an open-end wrench and set it off to the side. Locate the idle speed-control valve that is positioned at the base of the throttle body.
2. Detach the throttle body from the engine with a socket wrench and then separate the idle speed-control valve from the throttle body. Place the control valve on a towel or old cloth and coat the valve and throttle body with throttle body cleaner by spraying the cleaner on the inside and outside of the valve.
3. Clean the valve and throttle body by wiping it dry with a towel to remove any debris or oil. Spray a second coat of valve cleaner on the control valve and throttle body and use an old toothbrush to remove any remaining oil or gummy material from them. Wipe dry with a towel.
4. Verify there is no cloth material or any debris remaining on the parts and place the control valve back inside the throttle body. Attach the throttle body assembly back on the engine and secure with a socket wrench.
5. Place the air cleaner back on top of the throttle body and secure with an open-end wrench. Start the engine and verify the idle is operating better. There are, but, some matters you can act to aggrandizement sluggish quickness and ameliorate the performance of your vehicle. The inoperative velocity driver's seat (ISC) is bound for the process of the carburettor and meters the vastness of fuel that is allowed finished the operation. The hot potato is oftentimes a sticky or gummed-up speed-control valve. Cleaning the ISC valve will greatly increase any loss in rpm's and get your Rav 4 running more efficiently.
