Saab Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** model Saab do you have? What all has been replaced? Thanks.
Has anything been replaced yet? Thanks.
This usually means the Charge Air Bypass Valve has failed. The Black plastic Charge Air Bypass Valve (CABV) is located at the driver's side, front of the engine. It has two short, 1" diameter air bypass hoses and a vacuum control hose. Use mouth pressure and vacuum to test for leaks under both conditions. Any leakage requires CABV replacement. Let me know how it goes or if you have more questions, thanks.
