Can a damaged throttle cause a malfunction light?

Hello, according to what you said, this situation needs computer testing to see what fault code it is! And according to you, the cylinder pressure is high! It's no use cleaning the throttle! It is recommended to clean up the carbon deposit in the cylinder because there is too much carbon deposit in the cylinder, which leads to high pressure! You can add some fuel additives at ordinary times and try running at high speed!
