You definitely won't have a lambda sensor if it's got a carb. The sensor would be useless. In injected cars, the sensor's output is used to fine tune the air/fuel ratio. You can't do that with a carb. "Heikki Mastokangas" <> wrote in message > > Let me be stupid this time. I am wondering what kind of engine I have in > my SAAB.
