I have had a problem for a while were when I change gear abit more rapidly my revs don't drop as responsive as I want them to. I've been told it's normal so left it be, but today i noticed when I turn my ignition on there's a high pitch noise coming from the throttle body. I removed the pipe that connects to it and put a brick on the accelerator pedal to open the butterfly valve. I noticed the valve constantly vibrates/shakes/rattles like its trying to set itself? I did a throttle body reset last year when I first noticed the problem and NOTHING changed. Now if someone tells me that's normal then il stop trying to find something wrong with nothing lol. Cheers.
