Mine did this basically, it jerked seriously violently as soon as my foot touched the gas, and i couldnt imagine what it was. I figured out that it was the intake boot that's connected to the throttle body. When i squeezed it, my finger actually went inside. It was cracked all over the place, so i took it off, and temporarily wrapped it with a lot of duct tape. Then i went to BMW and got a new boot for like 30 bucks. Works like a charm now. So check all of your hoses THOROUGLLY, i know i checked mine, but only when i actually squeezed it did it fall apart. |
