1. Turn all the ignition switch but do not start the car.

4. Start the car for 10 minutes until it reads the valve code again.
You need to let this vehicle warm up every day for more than five minutes and do not replace any throttle body part if the pieces are not the original ones. Never move the screw that is next to the accelerator spring.
Other possible causes are: a vacuum leak in the intake manifold, dirty throttle body or damaged MAF sensor. Check them as well and, if the failure persists, check each relay and verify that the contacts, oxygen and air sensors are cleaned, and that there is no humidity in your vehicle. Finally, you can check the chain's tension. Hope my comments help you solve the problem.
