Ummm?
Are you sure that the hose is the sticking problem? Lots of black smoke is not a good thing. Assuming that the coolant hose was holding the throttle open then you might have a turbo problem or the IP has crapped out. Or...... Pull the intake off the turbo inlet and spin the turbine by hand. It should spin free with very little slack in the bearings. Did this all start after you adjusted the alda?
