P0171 code Volvo 850 GLT (97) 850 1997

Do you mean the waste gate? That is a non failing part. The yellow line should have a clamp that gives a nice snug fit.

You could also try spraying TB cleaner, starter fluid, butane, or some other flammable around suspect parts like the injector seals, the intake manifold gasket, etc and see if the idle changes.
