Subject: Re: Turbo going out?

I had this problem a few moths back. Turned out to be nothing more than a sticking wastegate! The boost gauge should never go into the red! If it does the over-pressure switch will kill the fuel/ignition. Hence the misfire. When the wastegate sticks closed you over-boost. When the wastegate sticks open, you get no boost. I managed to free mine by use of penetrating oil etc. My Saab tech. says this is common especially after the head-gasket has blown in the past. All the crud seems to collect and bake onto the wastegate spindle. Hope this helps, Pete. wrote in article <7a00it$4b$>... > I suspect my Turbo may be failing.
