I have a vacuum leak that I have not been able to find. I hear that this model had some problems with Vacuum. Is there a design flaw or weak point that others have found? How do I find Vacuum Leaks and where do I look for these leaks?

There is supposed to be at least 16 inches vacuum, but by the time it gets down to the transmission it is only 11 inches vacuum.

Have you checked vacuum at the intake?
