89 SPG NO BOOST, RUNS ROUGH AT LOW RPM

1989 SAAB 900

Engine Performance problem

I have a 1989 Saab 900 SPG. Just yesterday the car started running very rough at idle and low rpms and the boost gauge is at zero. I hear a whooshing sound from under the hood and the check engine light is now on. Any suggestions?

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on
