I haven't replaced the hose the Ts off from the AMM to the Turbo hose. It leads to the 'flametrap' nozzle (which is new). I replaced the hose leading from the nozzle to the oil trap (which I inspected and 'cleaned'.) I also changed the small hose from the trap to the intake manifold. This one may get replaced again. It appears too pliable and may collapse if a vacuum is applied.

Other hoses I haven't changed include the one T-ing off the metal hose on the intake side of the intercooler. It is connected to the Idle control valve. The hose from the valve to the intake manifold has also not been changed.

Those are ones I need to replace. They appear hard but intact.

What symptoms would a faulty control valve show? What about a throttle switch?
Thanks!
