i have a 2007 750i sport and when i'm driving around it seems fine but when i'm at a stop light it idles around 500 and i have to press the break harder then i feel like i should have to, also it feels like it torques up idk i feel like there's a overwhelming amount of torque when there shouldn't be at a stop light. my friend told me it looks like it is ready to launch like a sprinter in track when i put it into gear and hold the brake pedal.
