Hello my name is Jeff, and I'm new here. I have a 1992 camaro that i'm slowly restoring it and I need to find out if this car which has a V6 if it has a vaccume advance on it. Plus it has been tring to stall when it shifts into overdrive or goes up hill. I'm fixing to replace the fuel filters on it. But I'm at a loss about why it is tring to stall. Can any one give me some insight to this.
