Hi guys, One if the things I enjoy is mechanics and is very pleasant when I can solve problems by myself and save some money why not.
Here is my Toyota yaris' throttle valve which required maintenance for it was really dusty and sticky. This would cause "check engine" alarm and high vibration to the fuselage when starting the engine and remaining stopped.
When I finished cleaning the valve I had to face a new problem rpm's were around 1500 this was because I accidentally moved the valve and sensor calibration was lost.
After consulting Youtube and Facebook people I was recommend to disconnect the batery for 10 minutes and voilà problem solved.
I share you this experience in case you happen to have the same problem once.
