When I start the car, the idle stays normal for a bit then bounces up and down from 1k to 1.5k. There is a few things im not sure about. There is a hose coming straight out from the turbo, and its to the right of the turbine, I plugged it up(is that okay?). Theres another hose on the back of the engine that I plugged up. It came from the manifold. Theres also 3 hoses that connect to intake, but the one furthest to the right is plugged up, because the TID only has 2. If its not one of those, what can it be?

 

anybody
