Interesting thing I ust started noticing on my vehicle. When i mash on the accelerator down to the floor and let it up immediately, all this while cruising at any given speed, the engine revs upwards to 5500RPM for a minimum of 3 seconds. i ran this test because i was noticing a slight delay when starting from a standstill after i would start pressing on the accelerator. i have not ever experienced this in my 325xi. I'm taking my car into the shop tomorrow so they can hopefully diagnose and fix this. Anyone experience anything similar?
