    (Boost leak) mine had the same problem was a split underneath on the rubber joining the inlet manifold to the intercooler

    Did you notice behind you when you get this if there is black smoke coming out from behind you(over fueling)

    goes onto the airbox after the airfilter and measures the air passing through the pipe so it can calculate air fuel mix etc.....
