Hi everyone, my car does not seem to accelerate properly. On all gears, there is a threshold on the gass pedal where if i reach it the engine start to rev like crazy but the car just rolls for a second, not actually getting any faster and then the rev counter goes back where its supposed to and the car starts to gain speed for a second or two, until it happens again. If I release the gass pedal slighly it stops happening. I have this wideo to show gear 6 and then gear 5. The whole time revs go crazy in the wideo im keeping my foot on that threshold and not going any further until i need to slow down. http://videobam.com/YybQy By the way, does this small tube have to go somewhere important?
