vw passat 2003 2.0 is it okay to clean the throttle body while its fited in its place because its too hard to take it off and also affraid to break the butterfly. I saw alot of videos in youtube that they clean the TB in its place. I wanted to clean it because i dont feel alot of respond when accelrating. Thanks
