Does anyone have a clear vacuum hose diagram for a 2011 Saab 9-5 Turbo4? I get P0303 code and have replaced plugs, coil pack, checked wiring, has good compression, new fuel injectors found air intake pipe boot that connects to the turbo was shot and replaced it. Seemed fine for a minute but the rough idle is back with occasional blueish smoke. Any ideas or direction? Completely dumbfounded at this point.
